ABSTRACT:
This locking ring is adapted to lock a joint between two tubular elements (4, 8). It extends around a central axis (X-X) and comprises segments (50) each having a main part (58) and two circumferential ends (60). Each segment (50) has a shape flaring out from a thin axial side towards a wide axial side. One of the segments (50) comprises a recess (62) for receiving a retaining member (16), which is axially open on the thin side. The receiving recess (62) extends solely through the main part, and it is circumferentially limited on both sides.
