A coupling (10) for coupling two tubular elements in sealed relationship. The coupling (10) comprises a first tubular member (12) having an outer end (14) for connection to one tubular element, and having an inner end (16) comprising an axially extending locking sleeve (18), which has an annular gripping zone (20) having a plurality of annular gripping teeth (22) along its inner surface (24) and cam means (26) along its outer surface, and being radially compressible in the gripping zone (20). The coupling further comprises a second tubular member (30) having an outer end (32) for connection to another tubular element, and having an inner end (34) comprising an inner barrel (36), has further an annular locking piston (38) being axially displaceable relatively to the first tubular member (12) and the locking piston (38) having a locking zone (40) with complementary cam means (42) to cooperate with the cam means (26) of the gripping zone (20). |
