摘要 The shear-protected plug-in collar connection is intended for mouldings and for socketed pipes (1) which are produced using the centrifugal casting process and in the case of which the tip end (3) of the one pipe can be pushed into the collar end (2) of the other pipe with radial play. Arranged in the collar end are a sealing ring (8) and a clamping ring (14) which is constructed separately therefrom and has a large number of clamping segments (15) which are arranged with a mutual separation in the circumferential direction and have an outer jacket surface (17) of spherical construction and, on their inner surface (18), in each case one tooth system (19) which, when axial forces occur as a result of the interaction of the spherical jacket surface (17) with an inner surface (18) of the pipe collar (which tapers conically to the end), press radially against the tip end (3). An elastomeric retaining part (20), which can be fixed on the collar end and supports it, is integrally formed on the clamping ring (14). A design which ensures correct retention is achieved even in the case of relatively large nominal widths if the annular-disc-shaped section (23) of the retaining part, which comes to rest on the collar end surface (22), comprises in the region of the inner edge of the collar end surface (22) a transition region (26) which is of reinforced construction and has a higher bending strength, and from which the connecting section (24) which leads to the clamping ring (15) originates, and if the collar end surface (22) has, on the inner-edge side, a recess region which is matched to the cross-section of the transition region (26) which is of reinforced construction. In this case, a steel ring (28) which increases the bending strength and can possibly be inserted through an axial insertion gap (29) is allocated to the transition region (26) of the retaining part, which region is of reinforced construction. <IMAGE>
