The present invention provides a socket and a pipe joint which facilitate coupling and uncoupling of the socket and a plug and which can prevent the plug from jumping out of the socket in the uncoupling. In a socket 10 of the present invention, fluid in a built-in plug part 22 is released to the outside via communication holes 40 of a second base portion 18 and a through hole 51 of a third base portion 19 in a semi-inserted state. Accordingly, the pressure in a hole portion 34 does not become excessively high and an engaged part 42 is not unexpectedly pushed upward. Thus, an engagement portion 38 and a second engaged portion 26 can surely engage with each other. Hence, the plug 12 can be prevented from jumping out toward the front end side in the semi-inserted state.

A quick connector includes a socket having a socket opening and a plug inserted and coupled to the socket opening. The socket includes a socket body having a socket space into which the plug is inserted and a latch that hampers insertion of the plug into the socket space or stops the plug from escaping to the outside. The plug includes an insert body, an insert O-ring that surrounds the insert body, and an insert hook protruding outward from the insert body. The latch includes a latch frame, a latch opening formed in the latch frame, and a latch step that hides part of the latch opening, the latch step being disposed on the latch frame such that when the insert body is inserted into the socket space, the insert O-ring does not make contact with the latch step, but the insert hook makes contact with the latch step.

A tube coupling component (4;6) serves for use in a tube coupling system and an irrigation system. The tube coupling component (4;6) comprises a male coupling part (12) opposite a respective female coupling part (11), or a first end fitting (33) opposite a respective second end fitting (34), which tube coupling component (4;6) has an interior pipe (13;31) that extends axially inside an exterior pipe (14;32), wherein the interior pipe (13;31) and the exterior pipe (14;32) are concentric.

A plug-type coupling for connecting first and second fluid lines or a sub-assembly, which are designed with a mating plug-type coupling. The plug-type coupling including a housing including a sleeve section with a receiving channel (8) for axially receiving an adapter sleeve. The adapter sleeve being removably held in a positive-locking manner. The adapter sleeve includes a through-opening for a plug shaft of the mating plug-type coupling and a retaining means for removable attachment of the mating plug-type coupling. In an assembled state, the retaining means axially blocks the mating plug-type coupling with respect to the assembly axis. A locking element is arranged on an outer circumference of the sleeve section and is axially movable from a release position, which releases the retaining means, into a locking position, which locks the retaining means. In the release position, the locking element is fixed against axial movement into the locking position.

Provided is a quick connector assembly for joining a male member and a female connector member together to secure fluid communication in a fluid line system. The quick connector assembly includes a primary latch and a secondary latch configured to toggle between engaged and disengaged positions and to allow for a visual, audible, and/or tactile indication as to the status of a secure attachment between a male member and a female connector member.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a single-use, aseptic disconnection functionality that substantially prevents fluid spillage when being disconnected. In some embodiments, the coupling portions cannot be reconnected to each other after being disconnected from each other.

A hydration system including a fluid reservoir, a fluid path in communication with the reservoir, and a magnetic quick connect interposed in the fluid path is disclosed. A fluid delivery system for a hydration system is also disclosed that includes a magnetic quick connect interposed in a fluid delivery path of the delivery system. The magnetic quick connect can also be used in a wide variety of fluid delivery systems. A kit for forming a fluid delivery system for a hydration system is also disclosed, as are various components of a hydration system.

The invention relates to a connection assembly with a fluid plug and a fluid connector, said fluid connector being used to at least partly received the fluid plug. The connection assembly also comprises an electric plug and a receiving socket, wherein the receiving socket is used to at least partly receive the electric plug. The fluid plug and/or the fluid connector has a holder for the electric plug or the receiving socket, and the electric plug and/or the receiving socket is movably mounted relative to the other independently of a movement of the fluid connector and/or the fluid plug relative to the paired holder.

A coupling comprising a receiving element, a securing element, a retaining element and an insertion element, wherein the securing element is adapted to be displaceable between a release position and a locking position along a displacement axis, the securing element being adapted to engage the at least one retaining element in such a manner that a displacement of the securing element from the release position in the direction of the locking position is prevented, and wherein the insertion element is adapted to interact with the at least one retaining element upon insertion of the insertion element into the receiving space of the receiving element in such a way that a displacement of the securing element from the release position into the locking position is enabled.

An adapter for connecting components in a fluid system has an adapter body defining a cylindrical space and lock buttons which are biased into a locked position to secure the adapter to another component. The adapter body has a circular collar defining an inlet into the cylindrical space, a channel defining an outlet out of the cylindrical space, a support wall and a support flange defining one or more cutouts in an outer cylindrical side wall of the adapter body, and a slot defined between the collar and the support wall connecting the one or more cutouts to the cylindrical space. The lock buttons have a contact element positioned in one of the cutouts and an arm projecting positioned in the slot. The arms are partially in the cylindrical space in the locked position and are movable into an unlocked position when the contact elements are moved toward each other.
