Abstract:
A device for quickly coupling a tube to a rigid element (100), the device comprising a tubular endpiece (1) subdivided along its axis (2) into a first portion (3) for connection to the tube and a second portion (4) for coupling to the element (100), and fastener means (3.1, 15) for fastening the tube to the endpiece (1) and for fastening the endpiece (1) to the element (100), the second portion (4) of the endpiece (1) possessing a groove (8) for receiving a gasket (9) that is to provide sealing between said second portion (4) of the endpiece and the element (100), wherein the endpiece (1) is fitted with a protective sleeve (10) for protecting the gasket (9), which sleeve is mounted on the second portion (4) of the endpiece to slide along the axis (2) of the endpiece between a position where it covers the groove (8), in which position it protects the gasket (9) housed in said groove before and during coupling of the endpiece (1) to the element (100), and a disengaged position which is offset from the groove (8) towards the first portion (3) of the endpiece (1) so as to make it possible, prior to coupling, for the gasket (9) to be put into place in the groove (8), and after coupling for the gasket (9) to come directly into contact with the element (100).
