<p>The assembly has pipe sockets (1, 2) provided with locking ribs (12) coaxial with a center axis of the sockets, and a peripheral groove (13) formed behind the ribs. Flanges (8) of a spring band (3) are engaged behind the ribs, and are interrupted on a side of the spring band. Front flanks of the ribs enclose an angle alpha smaller than fifty degree with the center axis, where a radius of the smallest circumference of the front flanks is smaller than an inner radius of the flanges of the spring band. Projections are formed by bending up circumferential end sections of the spring band.</p> |
