BIGC:017 ABSTRACT COUPLING A locking slip coupling for coupling two tubular elements in sealed relationship. The coupling comprises a first tubular member having an outer end for connection to one tubular element, and having an inner end comprising an axially extending locking sleeve, the locking sleeve having an annular gripping zone defined by the locking sleeve having a plurality of annular gripping teeth along its inner surface in the gripping zone, having cam means along its outer surface in the gripping zone, and by the locking sleeve being radially compressible in the gripping zone. The coupling further comprises a second tubular member having an outer end for connection to another tubular element, and having an inner end comprising an inner barrel located within the locking sleeve. The coupling further has an annular locking piston which surrounds the gripping zone, the locking piston being axially displaceable relatively to the first tubular member between an inoperative position and an operative locking position, and the locking piston having a locking zone with complementary cam means along the inner surface of the piston in the locking zone to cooperate with the cam means of the gripping zone in the operative position of the piston to radially compress the gripping zone and thus compress the annular gripping member into sealing engagement with the inner barrel to lock the coupling.
