A coupling assembly includes pipe sockets of fluid-holding parts to be joined. The pipe sockets are each 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 at least one locking rib bounds a groove. The coupling assembly also contains a steel spring band, which is curved over more than 240° and whose axial ends have inwardly directed flanges which engage behind the locking ribs and are interrupted at least on the side of the spring band that lies opposite the circumferential ends of the spring band. The pipe sockets are fitted into each other and are sealed from each other. To simplify the handling of this coupling assembly and increase its ruggedness, 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; the axial width of the flanges corresponds to the width of the groove that holds them; and the spring band is noncorroding. |
