The fitting has a hollow cylindrical shaped retainer socket (3) with rotation synchronization bars (4a, 4b) comprising contact surfaces. A radial displaceable locking body is provided over a cut of the hollow cylindrical shaped retainer socket. Lateral ends of the rotation synchronization bars are provided at a specific distance from the lateral ends of the cut, where the distance is 1.5 times larger than diameter (D) of the socket. |
