DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
(39) Identical reference numbers and, in some cases, reference numbers marked with primes in the figures refer to identical or analogous elements.
(40)
(41) Spaced axially from the contact flange 14, the connection piece 10 is surrounded by a first threaded means, e.g., a ramp ring 16. The ramp ring 16 consists of two ramp sections, each surrounding approximately half of the circumference of the connection piece 10 at a 180° offset. The slanted areas of the ramp sections are located on the side of the ramp ring 16 facing away from the contact flange 14, i.e., at the bottom of
(42) A first safety latching means in the form of a horizontally projecting wing 18 can be seen above said edge in
(43)
(44) The half-ring segment 20 extends over an arc of approximately 180°. At its upper edge in
(45) A guide wing 26 whose linear guide element, e.g., a linear guide edge 261, extends in a tangential direction (relative to the associated segment end) can be seen in the axial gap between the clamping flange 22 and the ramp section 24. The linear guide edge 261 interacts with the linear guide edge 181 of the wing 18 on the connection piece 10, as shall be explained in greater detail below.
(46) Latching means extending in a tangential direction are embodied on both segment ends of the half-ring segment 20. On the segment end to the left in
(47)
(48) This relative orientation can be explained especially clearly using
(49) As may be seen in
(50) In the pre-assembly position, the half-ring segments 20 are thus secured to the connection piece 10 in a position that only permits the half-ring segments 20 to be pushed further towards one another. In this pre-assembly position, containers or filter capsules can be delivered with the connection piece 10 according to the invention. The end user can then connect an additional line section, as shall be explained in detail below.
(51) This is how the end user places the contact flange 31 of the other line section 30, in particular one shaped according to the conventional Tri-Clamp standard, onto the contact flange 14 of the connection piece 10. Then the two half-ring segments 20 are pushed further into one another, whereby their latching means 281, 282 slide deeper into one another and latch. In this position, the two half-ring segments 20 form a closed annular connection clamp 200. The clamping flanges 22 of their half-ring segments 20 engage behind the back shoulder of the contact flange 31 of the other line section 30. Their ramp sections 24 engage behind the ramp ring 16 of the connection piece 10, whereby the respective ramp slanted areas come to rest against one another. In the embodiment depicted, a mutual axial clamping force of the two contact flanges 31, 14 can already be applied in this position due to the conical design of the back shoulder of the contact flanges 31 of the other line section 30, which design is particularly apparent in
(52) For applying this clamping force, the arrangement of
(53) In the embodiment depicted, the half-ring segments 20 have two more additional features not yet discussed, which, firstly, provide the user with feedback that the final position depicted in
(54) Just before that, however, in the embodiment depicted the latching corner 182 must overcome a safety latching boss 29 disposed in front of the end stop 27. Said latching boss also represents a narrowing of the clearance of the connection clamp 200, which can be overcome, however, due to the material and/or form elasticity of the elements involved. Depending on the specific design, the safety latching boss 29 can be overcome uni-directionally or bi-directionally, the connection of the additional line section 30 to the connection piece 10 being either releasable or non-releasable.
(55)
(56)
(57) In addition, instead of the safety latching boss 29 of the half-ring segment 20 of the first embodiment, provided in the third embodiment is a latching rocker 29″ whose latching hook 291″ latches into a corresponding latching recess of the connection piece 10″ in the final position. Due to the rocker-type design of this type of safety latching means, the latch can be manually released, if necessary, by applying manual pressure on the release lever 293″ arranged on the other side of the rocker axle 292″.
(58) Apart from this, what has been described in the foregoing essentially applies, with analogous elements being marked with double primes, but otherwise identical in their reference numbers as used in

(60) Apart from this, what has been described in the foregoing essentially applies, with analogous elements being marked with triple primes, but otherwise identical in their reference numbers as used in
(61)
(62)
(63)
(64) The wall of the half-ring segment 20″″ has a through-opening in the shape of a slanted slot 241″″. This slanted slot 241″″ forms a second threaded means and is designed to interact with the first threaded means. The axial diameter of the slanted slot 241″″ largely corresponds to the diameter of the first threaded means 161″″.
(65) Latching means 281″″, 282″″ extending in a tangential direction are embodied on both segment ends of the half-ring segment 20″″. These take the form of latching tabs with a latching hook 291″″ oriented radially outwards on the right segment end in
(66)
(67) The
(68) In addition, the linear guide element 261″″ of the half-ring segment 20″″ has a latching clamp 40″″ at its front end that, in the pre-assembly position, applies a clamping force on the linear guide element 181″″, thus restricting both axial movement and rotation of the half-ring segment 20″″ relative to the connection piece 10″″.
(69) As may readily be seen in
(70) This way, the fitter, who is made aware of the latching process, e.g., from a corresponding latching sound, latching click, or in the form of a mechanical blockage, receives feedback about whether he has adequately arranged the half-ring segment 20″″ on the connection piece 10″″.
(71) This is how the end user places the contact flange 31 of the additional line section 30, in particular one shaped according to the conventional Tri-Clamp standard, onto the contact flange 14″″ of the connection piece 10″″. Then the two half-ring segments 20″″ are pushed further into one another, their latching means 281″″, 282″″ sliding deeper into one another until the two half-ring segments 20″″ form a closed annular connection clamp 200 in this position.
(72)
(73) This way, the fitter, who is made aware of the latching process, e.g., by a corresponding latching sound, latching click, or in the form of a mechanical blockage, receives feedback about whether he has adequately joined the half-ring segments 20″″.
(74)
(75) During this rotation, the interior sides of the linear guide element 261″″ of the half-ring segment 20″″ as well as the interior sides of the second threaded means 241″″ interact, like a threaded connection, with the linear guide element 181″″ of the connection piece or with the first threaded means 161″″ so that the connection clamp 200 is drawn in an axial direction towards the connection piece 10″″. In this process, the clamping flange 22″″ presses against the rear shoulder of the contact flange 31 of the additional line section 30, drawing it to the contact flange 14″″ of the connection piece 10″″. This results in sealing clamping of the two contact flanges 14″″, 31.
(76) In the present embodiment, the half-ring segments 20″″ can be returned to the pre-assembly position from the final assembly position in that a force is applied on the release levers 293″″ of the latching means 281″″ of the first type, thus moving the latching hooks 291″″ out of the latching recesses 43″″, allowing the half-ring segments 20″″ to reposition away from one another in a tangential direction.
(77) Apart from this, what has been described in the foregoing essentially applies, with analogous elements being marked with quadruple primes, but otherwise identical in their reference numbers as used in

(81) The half-ring segment 201′″″ depicted in
(82) In addition, the depicted half-ring segment 201′″″ has, on both segment ends, linear guide elements 263′″″ that are embodied as through-openings and are designed such that corresponding linear guide elements 262′″″ of another half-ring segment 202′″″ can engage and latch in the linear guide elements 263′″″.
(83) The linear guide elements 263′″″ are arranged at different positions on each segment end. While the linear guide element 263′″″ on the right segment end depicted in

(86) In addition, the depicted half-ring segment 202′″″ has, on both segment ends, linear guide elements 262′″″ that are embodied in the form of latching tabs with a latching hook 291′″″ oriented outwards. The latching hook 291′″″ is not oriented radially outwards, but instead, is arranged slightly tilted on the half-ring segment 202′″″.
(87) The linear guide elements 262′″″ are arranged at different positions on each segment end. While the linear guide element 262′″″ is arranged in the upper corner of the segment end on the right segment end depicted in

(90) Additionally, in this position the latching hook 294′″″ is latched in a latching recess 42′″″ disposed on the interior side of the latching means 282′″″ of the second type.

(95) Of course, the embodiments discussed in the specific description and shown in the figures are merely illustrative exemplary embodiments of the present invention. In the light of the present disclosure a person skilled in the art has a broad spectrum of optional variations available. It will be obvious to the person skilled in the art that it is not absolutely necessary to follow the Tri-Clamp standard, which has been cited here repeatedly. Due to the wide proliferation of this standard, such a considered particularly advantageous, however. Adaptations to certain variants of the standard (e.g., Sanitary F, Sanitary S) are just as possible as are adaptations to other standards.
