ABSTRACT:
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.
