Abstract
A mechanical coupling for immersed pipelines, of which one has a collar at its end. The device comprises a toothed counter-flange (3) placed against the collar (1a) of the tube to be repaired (1), a tubular body (2) welded by one end to the end of the tube to be assembled with the tube to be repaired (1) provided at its opposite end with an annular abutment (4) and on which tubular body (2) is placed by locking means (5), a mobile assembly comprising a spacer (6) forming the mobile jack body and an internal annular shoulder (6a) of which serves as a piston and defines at least one jack chamber, said spacer (6) cooperating at one of its ends with said locking means (5) and carrying at its other end a toothed flange (7) associated with resilient clamping maintenance means (8), as well as means for moving the locking means (5).
