ABSTRACT:
The present coupling is intended to connect a tubular member to a further member such as a coupling sleeve or the like. The further member has an aperture for insertion of the tubular member and a hole extending substantially tangentially relative to the aperture and in partial overlap with the aperture. A locking pin with a flattened side region is inserted into the hole and then rotated to interlock the tubular member and the further member by deforming the tubular member. The locking pin may, for example, be a hollow sleeve with a longitudinal slot in the wall of the sleeve to provide said flattened region. The edges adjacent to the slot in the sleeve may be bent inwardly to facilitate the rotation of the sleeve type locking pin.
