An embodiment of a fluid valve includes a substantially flat face plate, a receptacle, a cavity, and a drain assembly. The receptacle is disposed in the face plate and has at least one protrusion each configured to engage a respective one of at least one groove of a valve-opening-and-fluid-dispensing device. The cavity has a top end in fluid communication with the receptacle, and has a bottom end. And the drain assembly has a top end in fluid communication with the bottom end of the cavity, has a bottom end, and is configured to allow fluid to drain from the cavity in response to the valve-opening-and-fluid-dispensing device being absent from the receptacle.

An assembly of a male coupling part 200 and a stiff tube 100 is disclosed, the stiff tube 100 having an attachment means 110; and the male coupling part 200 requiring a relative axial displacement between the male coupling part 200 and the stiff tube 100 for connecting to a female coupling part 500, the male coupling part 200 comprising an axial through opening 210. The Assembly further comprises an element 300 detachably connected to the male coupling part 200 and slidably attached to the stiff tube 100, the element 300 having an opening 310 allowing relative axial displacement 340 between the male coupling part 200 and the stiff tube 100, and the attachment means 110 being movable within the opening 310. A method for coupling and un-coupling the assembly to a female coupling part is also disclosed.

A fitting for use in a manifold or other tubular assembly includes a core and at least one tubular coupling sleeve slidably and sealingly fitted over a distal end of the core to accommodate predetermined tolerances in the relative positions of fluid ports connected with the tubular assembly. Features are provided to limit the range of motion to the predetermined tolerances and to prevent disassembly of the coupling sleeve from the core of the fitting.

Disclosed is a fluid connection device (10) comprising a male connector (12) and a female connector (14), which are configured to be fitted one inside the other along an axis X so as to produce a fluid connection, and at least one annular seal (16) carried by one of the connectors and configured to engage with the other connector in order to ensure a seal between the connectors, the connectors being configured to be fastened to each other by resilient snap-fastening and to retain, after fastening, at least one degree of freedom with respect to each other, characterised in that the connectors are fastened together by a double fastening by resilient snap-fastening and by bayonet, this resilient snap-fastening being configured to be irreversible without deterioration so that, after fastening, the device cannot be dismantled without deterioration.

An aircraft fluid line coupling assembly includes: an inner tube; an outer tube assembly having an outer tube, the inner tube extending into the outer tube, and having first connector element of a twist-to-connect joint disposed on a front end of the outer tube; a retention member having second connector element of the twist-to-connect joint, the first and the second connector elements being detachably mated to releasably interconnect the retention member and the outer tube with each other, the retention member being arranged outwardly around a longitudinal portion the inner tube so as to prevent detachment of the inner tube from the outer tube when the twist-to-connect joint is in a connected position, and so as to allow detachment of the inner tube from the outer tube when the twist-to-connect joint is in an unconnected position; and a locking mechanism for locking the twist-to-connect joint.
