Abstract: In a clamping sleeve for pipes, which consists of a rubber-elastic sealing ring and a clamping ring (2) encircling the sealing ring, on the ends of which clamping ring (2) are attached parts (4, 5) having clamping plates directed outward and located opposite one another, the gap between the clamping plates is bridged by a sheet-metal part which sits against the outer side of the clamping ring and, like the clamping ring (2) itself also has edges which are bent radially inward and, at the overlapping point with the end of the clamping ring (2), fit between the bent edges of the clamping ring. The sheet-metal part (15) is formed by an end section of the clamping ring (2) which has a longitudinal slot (18) which extends up to its end and, in turn opens at its inner end into a transverse slot (19).
