A connector, having a socket part and a plug part being insertable into a socket section of the socket part, wherein the plug part is provided with a retaining element for detachably retaining the plug part in the socket part, the retaining element having a retaining arm with at least one outwardly projecting engaging catch, a free end, and an end secured to the retaining element body and can be spring-elastically moved in the radial direction in relation to the plug part for blocking the engaging catch on a blocking surface or a blocking opening of the socket part and releasing it from same, and a locking device being provided for securing the blocking status of the plug part and socket part and for indicating an incorrect assembly thereof, the locking device cooperating with the retaining element, and being a radially insertable locking element that cooperates with the retaining element in the region of the retaining arm thereof.

A hand disassembly rotational valve coupling for tool less manipulation by a user's hands and fingers using a coupling housing body defining an output seal aperture close to an output handle retention slot and slot lip, where the slot lip has a slot handle gap and an output seal retainer including a coupling handle ring with a first triangulated offset body retention ears and hand graspable handles separated by a ring handle gap for hand assembly and disassembly from the coupling housing body.

Tube retainers, tube retainer sets, and tube management systems comprising blocks with male and female block connectors, and methods of assembling and using the tube retainers, sets, and systems, are disclosed.

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 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.

A connection assembly is used to connect a first body to a second body. The first body includes a bore that is coaxial with a first axis, and a retainer opening that extends coaxially with a second axis. The second axis is perpendicular to the first axis and offset relative to the first axis. In addition, a portion of the retainer opening intersects the bore. The second body includes an insertion portion that is disposed in the bore, a fluid passage that extends through the insertion portion and communicates with the bore, and an outer surface of the second body has a channel. The connection assembly employs an elastic retaining pin that retains the insertion portion within the bore. The retaining pin is disposed in the retainer opening such that a portion of the retaining pin resides in the channel, and the retaining pin is self-aligning and self-retaining.

A fluidic connection device for a fluid circuit of a motor vehicle includes a female fluidic connector, a U-shaped lock, and a locking indicator. The female fluidic connector includes a housing configured to receive a male fluidic connector, by translation along an axis (A). The U-shaped lock is carried by the female connector and includes a pair of elastically deformable legs that arranged substantially in a first plane, perpendicular to the axis (A) and on either side of the axis (A) and being configured to cooperate by elastic snap-fitting with the male connector to ensure retention of the male connector in the female connector along the axis (A). The locking indicator is carried by the female connector and configured to be translated in a second plane, perpendicular to the axis (A), between a first position for releasing the locking indicator and a second position for locking the locking indicator.

A quick connector structure includes a fitting connector, a connector, and a U-shaped positioning snap pin. The fitting connector is a pipe connector, a three-way valve connector, or a washing machine valve connector. The fitting connector is combined with a pipe body. The U-shaped positioning snap pin ensures the stability of the connection between the fitting connector and the connector. The quick connector structure enables rapid positioning and assembly, reducing the assembly difficulty in a smaller or concealed space and achieving the effects of assembly stability and convenience.

The disclosure herein relates to a quick-connect fitting that provides a leak-proof connection between two components of a waterway. The quick-connect fitting of the present disclosure is releasable and reusable for disconnecting and reconnecting the waterway connection. Moreover, the quick-connect fitting further comprises an audible identifier which identifies the quick-connect fitting has secured the waterway components to be connected.
