This disclosure relates to a quick connector adapted to display a code that verifies that a latch member is engaged to retain an installed pipe to the quick connector. The quick connector comprises a connector body having a receiving portion surrounding an internal passage, the internal passage arranged to receive the pipe therein. A latch member retained on the receiving portion is arranged to be movable between a pipe insertion position and a latched position. In the pipe insertion position, the latch member allows the pipe to be inserted into the internal passage. A code readable by a scanning device becomes readable when the latch member is moved to the latched position verifying that the pipe is installed and latched in the connector body.

The disclosure relates to a plug connector and method for connecting pipes for liquid or gaseous media. The plug connector includes a connector body and a locking element. An indicator element is formed, which has an indicator surface, a first partial section and a second partial section, wherein the first partial section and the second partial section are flexibly coupled to one another by means of a spring section. The first partial section is connected to the locking element, and the indicator surface is formed on the second partial section, wherein the indicator element is formed such that, in a locking position of the locking element, the second partial section is deformed relative to the first partial section, so that the indicator surface is pushed into an indicator position.

A joint body has tube connection holes each having an inner circumferential surface including a plurality of contact walls, which are equiangularly spaced about an axis of the tube connection hole and extend along the axis. A joint guide is cylindrical and includes a barb on its outer circumferential surface. The joint guide is configured such that, when the joint guide is press-fitted into the tube connection hole, the outer circumferential surface of the joint guide comes into contact with inner wall surfaces of the contact walls and the barb catches the contact walls.

A fluid connector, including a tubular member, a connector body, including an exterior opening groove, and a retainer clip to lock the tubular member to the connector body, an assurance cap including one or more latch fingers engaged with the exterior opening groove, and a tool, including an annular collar mountable over the tubular member, and a plurality of fingers carried on and extending axially from the annular collar, the plurality of fingers operatively arranged to engage the latch fingers when the collar and the plurality of fingers are engaged with the assurance cap to disengage the latch fingers from the exterior opening groove to disconnect the assurance cap from the connector body.

A fluid circuit, in particular for an aircraft, having at least a first pipe, a second pipe and a connecting fitting, each pipe having a connection end and extending along an axis X, the connecting fitting, movably mounted between the two pipes, being configured to mechanically connect the two connection ends, the connecting fitting having a connecting sleeve and a guide member formed on an outer surface of the connecting sleeve and configured to cooperate with a heater duct so as to guide it between the two pipes, the heater duct being configured to transmit heat to the pipes and to the connecting fitting so as to prevent them from icing up.

A connector includes a connector body having a hollow channel, and a retainer configured to prevent a pipe inserted into the hollow channel from being removed using a stopper piece. The retainer body lies along the outer peripheral surface of the retainer attachment portion. A bearing allows the retainer body to rotate from a temporary locking position to a main locking position. A detection piece passes through a detection hole and projects into the hollow channel when located in the temporary locked position, so as to be pushed in an axial direction by a bulge of the pipe. An inclined surface of the detection piece inclines with respect to the axial direction such that a pushing force can be converted to a radially outward force. A first energy conversion mechanism serves to convert the energy converted by the inclined surface to the rotational energy in the locking direction.

A quick connector assembly and process for forming a coupling in a fluid line between a first and a second fluid tube comprises a receptacle body having a cavity extending through the receptacle body to the second fluid tube. A sealing section is located within the cavity and a socket portion extends from the sealing section. The socket portion includes wall bordering a socket opening in alignment with the cavity and includes a pair of latch openings extending through a portion of the wall into the socket opening. A sealing member having a receiver opening is installed in the sealing section with the receiver opening in alignment with the socket opening and the cavity to the second tube. A bracket installed on the wall includes a pair of spring latches, each spring latch extending through a respective one of the pair of latch openings into the socket opening. A first fluid tube having an insertion portion and a raised upset is placed through the socket opening into the receiver opening making a fluid connection to the second fluid tube and causing the upset to be captured by each spring latch. A verifier having fixing fingers and a pair of arms is installed through respective recesses in the wall into the socket opening. Upon the capture of the first fluid tube upset by the spring latches, a force applied to the verifier causes each verifier arm to travel along the upset to rest below a respective spring latch and the fixing fingers to also capture the upset. Verifier symbols located on a surface of each verifier arm are visible through each latch openings verifying that the first fluid tube has been coupled to the receptacle body.

A tube coupling including a female connector a body into which a male connector having an annular collar is inserted axially, and a connection element is provided. The connection element extends in a transverse direction within the body of the female connector. The connection element is designed to interfere mechanically with the collar during insertion of the male connector and to move transversely of its own accord towards the inside of the female connector. The connection element includes a locking hook that cooperates with a locking catch provided in the female connector. The hook goes past the catch as a result of the mechanical interference of the collar that drives axial and radial elastic deformation of the connection element. The hook locks against the catch when the connection element is fully pushed into the female connector.

A connector is disclosed that includes a coupler having a socket end fluidically connected by a passage to a stem connected to a first fluid tube. A retainer housing having a cavity in axial alignment with the passage is installed on the coupler socket end and a retainer is installed in the retainer housing in a first position. A second fluid tube having a raised bead formed proximate an end portion of the second fluid tube is permitted to be installed into the retainer housing cavity by the retainer when the retainer is in the first position. Installation of the second fluid tube places the bead in the retainer housing and the end portion of the second fluid tube in the coupler passage providing a fluid path between the first fluid tube and the second fluid tube. The retainer is moved to a second position latching the bead to the retainer housing retaining the second fluid tube to the connector.

The invention relates to an annular connection clamp with a first clamping flange (22) which protrudes radially inwards and with an axial counter bearing (24) which is spaced from the clamping flange and which is made of a first and a second half-ring segment (20), each half-ring segment having a first and a second segment end. The first segment end of the first half-ring segment (20) has latching means (281) of a first type, and the second segment end of the second half-ring segment has corresponding latching means (282) of a second type, said latching means being pushed into each other in a tangential direction, thereby being latchable together. The second segment end of the half-ring segment (20) has latching means (282) of a second type, and the first segment end of the second half-ring segment (20) has latching means (281) of a first type, said latching means being pushed into each other in a tangential direction, thereby being latchable together.
