ABSTRACT:
A coupling assembly includes pipe sockets of fluid-holding parts to be joined. The pipe sockets are provided with a peripheral locking rib, behind which a groove is formed and which has a conical front flank and a radial rear flank. The front flanks of the locking ribs lie opposite each other. The rear flank of one locking rib bounds a groove. The coupling assembly also contains a steel spring band, which is curved more than 240° and whose axial ends have inwardly directed flanges which engage behind the locking ribs and are interrupted on the side of the spring band opposite the ends of the spring band. The front flanks of the locking ribs enclose an angle <50° with the center axis, the radius of the smallest circumference of the front flanks is smaller than the inner radius of the flanges of the spring band.
