The invention provides a pre-assembled coupling for leaktight coupling of a fluid transport tube and an endpiece provided with at least one coupling element. The coupling comprises: a said tube, which tube presents an annular bead at a front end; a fastener device slid onto said tube and presenting at least one fastener element complementary to a fastener element of the endpiece; and an elastomer sealing element disposed around said tube and presenting an inner surface for providing sealing with an outer surface of the tube, and an outer surface for providing sealing with the endpiece. The invention is particularly suitable for fluid circuits in motor vehicles. |
