ABSTRACT:
An adapter for releasably coupling two tubular elements comprises a socket, a sleeve nut threadedly engaging the socket and an elastically deformable sleeve inserted in the sleeve nut. The socket consists of a smaller diameter and a larger diameter part, and the sleeve nut has an inner thread in threaded engagement with an outer thread on the larger diameter socket part. The axial length of the sleeve nut exceeds that of the larger diameter socket part, the inner thread is arranged at one sleeve nut end and an inwardly extending flange is at the opposite sleeve nut end. The sleeve is inserted in the sleeve nut between axially spaced shoulders formed by the flange and the larger diameter socket part. The outer diameter of the sleeve is slightly smaller than the inner diameter of the sleeve nut, the periphery of the sleeve defines a circumferentially extending trough-shaped recess, and the sleeve has a cylindrical inner wall.
