Provided are pipe systems and methods for assembling the same. A pipe system includes two pipes, each having an axis, an exterior surface, a retainer groove formed in the exterior surface, and a sheath mounted to a respective pipe such that the sheath at least partially covers the retainer groove prior to assembly. A retainer is also located in the each retainer groove, disposed radially beneath the sheath relative to the axis, prior to assembly. The system further includes a coupling having a bell configured to receive each of the two pipes. Each bell may have a retainer groove formed in an inner surface thereof and the bell configured to receive at least a portion of a respective retainer after assembly of the pipe system. When assembled, the sheaths are configured to uncover the retainer grooves such that the retainers expand into the retainer grooves of the coupling inner surface.

The invention relates to a connection unit for connecting fluid lines, wherein the connection unit comprises a first connection body and a second connection body, wherein the connection unit comprises a machine-readable code which is not detectable when the first connection body and the second connection body are in an unconnected state and which is detectable when the first connection body and the second connection body are in a connected state.

A valve connector includes a housing and a pressing device. The housing includes an operative end, a coupling end, and a through-hole extending from the operative end through the coupling end. The pressing device includes a push seat received in the through-hole and located between the lever and the coupling end and a lever abutting against the push seat and pivotably connected to the housing. The push seat includes a first passageway. The lever includes a second passageway and is operable to move the push seat. When the lever is in a release position, the first passageway does not intercommunicate with the second passageway. When the lever moves from the release position to a locking position, the push seat moves towards the coupling end, and the first passageway intercommunicates with the second passageway when the lever is in the locking position.

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 quick connect fitting kit includes a chuck having a threaded end. The chuck defines a channel. A collar has a threaded end and a sloped inner surface. The threaded end of the collar is meshable with the threaded end of the chuck to mount the collar to the chuck. A collet has a sloped outer surface. The collet is positioned within the collar such that the sloped outer surface of the collet is positioned on the sloped inner surface of the collar. The collet defines a passage. The passage of the collet is sized for receipt of a pipe. The pipe is in fluid communication with the channel of the chuck when the collet is compressed against the pipe and the collar is mounted to the chuck.

A pipe joining system and pipe joint are shown in which two sections of plastic pipe, particularly molecularly oriented pipe, are joined. A ring-shaped elastomeric body is installed within a mating groove provided in a mouth region of female pipe section. The ring-shaped body is formed of an injection molded elastomeric material which is joined to a series of arcuate gripping segments which have teeth on an inner surface thereof which are designed to engage an outer surface of a mating male pipe section to restrain movement of the male pipe after assembly of a pipe joint. The gripping segments are separated by a gap which is open prior to assembly, but which closes during assembly. Each of the segments also has a positive stop feature to prevent over travel of the male pipe section relative to the female pipe section.

A tamper-evident cover for a component, the component comprising: first and second portions; and an actuator mechanism for moving the first and second portions or allowing the first and second portions to move relative to one another; wherein the cover comprises: a cover portion defining a cavity configured to receive the actuator mechanism of the component so as to prevent access to the actuator mechanism from the exterior of the cover portion; and a retention barb connected to the cover portion and housed within the cavity formed by the cover portion such that it is inaccessible from the exterior of the cover portion, the retention barb being configured to engage with the component so as to retain the cover portion over the actuator mechanism.
