Abstract:
A coupling arrangement having external threads carried on a first pipe element. A second pipe element carries a radially movable locking member with external locking profiles, and a connection sleeve having internal threads that are threaded onto external threads and internal locking profiles that engage with the external locking profiles. The connection sleeve is moved in a first axial direction towards the first pipe element by rotation on the external threads while the internal locking profiles are in an intermediate engagement with the external locking profiles, until the movement is limited by abutting faces of the internal and external locking profiles. At least one of the abutting faces exhibits an inclination resulting in a pull of the connection sleeve towards an axial direction opposite of the first axial direction when the external locking profiles are moved radially.
