The connector consists of a coupling member (2) which is fitted to the end of the tube and made with an annular recess (5) in its end face to receive a collar (8) on the tube and a seal ring (10). The edge of the annular recess has an inward-facing lip (6) which acts as a retaining element for the seal ring. The connector is made by fitting the coupling member onto the tube end and then deforming the end of the tube to make a collar inside the coupling member's recess, using a shaping tool which forms the collar, the lip and the recess for the seal ring. |
