Abstract
A pipe coupling has a cylindrical housing which is split in the longitudinal direction and has inwardly bent end walls and a steel insert sheet of analogous design bridging the gap in the housing. With the aid of a closure with tensioning screws, the housing can be constricted in the manner of a pipe clip, such that a sealing sleeve positioned between the housing and a pipe is compressed in the circumferential direction and brought to bear on the pipes to be sealed off. The closure is offset in the circumferential direction with respect to the housing gap, and the end section of the housing projecting through the region of the tensioning screws is overlapped by a slideway anchored on the other end section. By this means, dimensional stability is increased without increasing the wall thickness, or the constrictability of the housing is guaranteed despite an increased wall thickness.
