摘要： The invention relates to a coupler comprising a tubular body (6) which is disposed so as to receive a tubular fluid transfer element having a pipe end and which is provided with means for locking (11) said tubular element. Moreover, the inventive coupler comprises a bushing (15) having means (23, 25) disposed therein which are used to support the pipe end and which can be selectively activated and deactivated. The invention is characterised in that the bushing is mounted in the tubular body so that it can move axially between one position in which the support means are activated and another position in which the support means are deactivated. Furthermore, said coupler is characterised in that the bushing is provided with locking means which complement those of the body and which co-operate with same in the activation position.

摘要： The washer for an instantaneous connection comprises a cylindrical base (8) with several teeth (9) located on a conical surface housed inside the cylinder. Each tooth comprises a root (9a) parallel to the base axis. The edge (8b) of the base opposite the root is raised outwards. An Independent claim is included for a connection part using the washer.

摘要： The joint comprises a tubular insert (1) with external anchoring elements (7) for engaging with the inner surface (107) of a recess (105) in the rigid component (103), a retaining member for the tube (101) and a seal (25). The insert (1) has a nose (21) with an outer diameter smaller than that of the anchoring elements, and a guard ring (23) with an inner diameter similar to that of the nose, with the ring mounted on the free end of the latter and fixed axially by a locking member (27), with the seal (25) inside the ring. The guard ring locking member has a connecting zone of low mechanical strength, e.g. with a peripheral groove. The joint also has a tubular pusher (13) which slides inside the insert to control the release of the retaining member (11).

摘要： The coupling consists of a tubular body (1) with one end connected to a pipe or other associated equipment, and the other containing deformable claws (12) and a seal ring (8) set in an annular recess (3) formed between stepped cylindrical surfaces. The seal ring has a toroid first surface (9) which interacts with the outer surface of the pipe, an outer cylindrical second surface (10) interacting with the inner cylindrical surface of the coupling body, and an inner conical third surface (11) which acts as a wedge to hold the claws in their gripping position. A pressure element (15) is used to open the claws for removing the pipe.
