A push-in tube connector port for connecting a tube to a pressurized fluid system is provided. The push-in port includes a central recess for receiving the tube, a sealing arrangement inside of the recess, a locking ring engaged within the recess, and a tube gripping ring having an inwardly directed gripping edge. The locking ring has a U-shaped cross-section. A number of circumferentially distributed slots subdivides an outer ring wall of the locking ring into a number of outer ring wall portions configured to be elastically deflected towards the center by the flange of an insertion end opening, when the annular double ring component is pressed into the recess, and to elastically flex back outwardly once the outer ring wall portions have passed the flange such that an upper edge of each of the outer ring wall portions engages an inner surface of the flange to secure the locking ring in the recess.

A device for connecting two tubular objects has a connection piece housing and a securing element. The securing element is shaped in a complementary manner with respect to a receiving opening of the connection piece housing and is arranged rotatably in the receiving opening and has an insertion opening for receiving a connection piece. The securing element has securing tabs which are spaced apart from one another in the circumferential direction and each have a radially inwardly facing securing body for engaging in shaped features of a connection piece and can be moved from a first position into a second radial position lying radially on the outside. The connection piece housing has, for each securing tab, a ramp surface which is bevelled radially inwards and on which the securing tab rests.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a sterile connection for drug delivery. In some embodiments, the fluid coupling devices can be implemented as multi-use, sterile fluid coupling devices that are configured to reduce the likelihood of fluid spillage when being disconnected.

A connection unit for connecting fluid lines, including a plug-in unit connectable to a first fluid line not belonging to the connection unit, defining a first fluid flow channel in its interior, and a receiving unit connectable to a second fluid line not belonging to the connection unit, defining a second fluid flow channel in its interior. The plug-in unit and the receiving unit are connectable to establish a fluid connection between the first and second fluid flow channels. The connection unit also includes a release element transferrable from a holding state to a release state upon insertion of the plug-in unit into the receiving unit up to a predetermined depth, and an indicator element formed separately from the release element and locked by the release element in the holding state. The indicator element is detachable from the connection unit when the release element is in the release state.

Quick connector having a coupling body and a multifunctional part with a retention unit and an indicator. The coupling body includes a head portion at one end and a plug-in portion at the other end, the plug-in portion configured for attaching to a first tube, the head portion having an axial opening for introduction of a counterpart with a circumferential collar. The head portion has at least one radial opening for inserting the multifunctional part, the multifunctional part having a back for manual operation for the purpose of being inserted into the coupling body. The retention unit has two retention legs, and the indicator has two indicator limbs movable independently of the retention legs when inserting the circumferential collar. The indicator limbs and the coupling body are configured so that the indicator can be transferred from a partially inserted preassembly position to a fully inserted assembly position via movement of the indicator limbs.

A pipe connecting connector adapted to connect a pipe to a connecting object, includes a connector main body adapted to insert or remove the pipe, and including a locking opening formed on a side portion thereof; a lock member including an annular portion and a pipe locking portion extending from the annular portion and including a locking claw extending inside the connector main body through the locking opening for locking the pipe, the lock member being movably held relative to the connector main body between a locking position wherein the pipe locking portion locks the pipe, and an unlocking position releasing the locking, and an urging device urging the lock member to a locking position side. The pipe locking portion is urged in a locking direction of the pipe by an urging force of the urging device when the lock member is in the locking position.

A connecting device for connecting two or more components to one another, includes an inlet section and an outlet section. The inlet section and the outlet section respectively include one or more connectors for each of the two or more components, with one or more passages extending between the inlet section and the outlet section, with the connecting device being of single piece design and being plastic.

A fluidic connection assembly and methods for quickly connecting or disconnecting a tube to a port by hand and without the use of tools. A body is adapted to receive a tube therethrough, and may have at least two sides which are hinged. Each of the hinged sides has corresponding latching portions or projections located near a lower end of the body. These projections are adapted to fit into a port or other fitting and be securely held in place. The assembly may include a tube extending through a body and through a spring located between the end of the body and the end of the tube, whereby the spring exerts a force directly or indirectly against the end of the tube and against the body, thus holding the tubing securely and sealingly engaged in the port when the assembly is connected. The body may further comprise an additional body or an adapter, and/or a cap and latch. A second spring may be used to push a projecting member into a groove or notch of an adapter when an end of the adapter is inserted into one end of the latch or the body. The fluidic connection assembly is useful in analytical instrument systems, such as for in vitro applications and/or in high pressure applications, among other things, and may be used in methods for connecting, or disconnecting, tubing or a fluidic connection assembly from a port or other fitting or connection.

A quick connector assembly connects to and establishes fluid communication with a male end port. The quick connector assembly includes a female component and an internal clip carried by the female component. The quick connector assembly receives the male end port in a single predetermined rotational orientation for retaining the male end port and the quick connector assembly non-rotatable receives the male end port.

A coupling for an irrigation system may have a first member and a second member, each of which has threads that engage a threaded fitting of an adjacent component. The first member may have a shank and a flange that has a greater exterior dimension than the shank. The flange may have a first locking extension. The second member may have a bore that receives the shank such that the second member is slidable along the base member between a locked configuration in which rotation of the second member about the centerline induces rotation of the base member about the centerline, and an unlocked configuration, in which the second member is rotatable about the centerline independently of rotation of the base member. The second member may further have a first recess that receives the first locking extension in the locked configuration.
