A clamping sleeve for pipes consists of a rubberelastic sealing ring (1) and a clamping ring (2) which encircles the sealing ring and has clamping plates (5) which are directed radially outward, are located opposite one another and are penetrated by a centrally arranged clamping screw (6). The clamping screw (6) is supported on the clamping plates by intermediate pieces (8, 9), of which one is arranged between the head (7) of the clamping screw and the clamping plate, whereas the other directly forms the nut for the clamping screw. The intermediate pieces (8, 9) have a cylindrical cross-section, so that they sit with a cylindrical surface against the adjacent clamping plate (5). Furthermore, the position of the intermediate pieces (8, 9) is fixed at the clamping plate (5) by stops (11, 12). The swivelling capacity of the intermediate pieces (8, 9) relative to the clamping plates (5) makes possible an inclined position of the clamping plates (5) relative to the clamping screw (6) and relative to one another. In this way, despite the use of only one clamping screw, perfect seating of the clamping sleeve is also ensured when pipes to be connected to the clamping sleeve have different diameters within the tolerance range.

In a clamping sleeve for joining pipes which may be of differing diameters and having a rubber-elastic sealing ring which has at least one beading projecting radially inward at each of its ends, a clamping ring which encircles the sealing ring and is in the form of a sheet-metal strip bent in a circular shape about a central axis and on the ends of which are attached opposing clamping plates which extend generally radially outward, and clamping means for drawing the clamping plates toward each other to secure the clamping sleeve in clamping engagement with pipes to be joined and including a clamping screw extending through the clamping plates, the improvement wherein said clamping means includes a pair of intermediate pieces, each of said intermediate pieces being received on said clamping screw outward of an associated one of the clamping plates, each of said intermediate pieces being at least partially cylindrical and defining a partially cylindrical bearing surface engaging an associated one of said clamping plates, each of said intermediate pieces being arranged with the axis of its partially cylindrical bearing surface being parallel to a plane that is perpendicular to said central axis.
