ABSTRACT:
A clamping ring for use in pipe joints has an inside surface which is formed with generally peripherally extending indentations for axially fixing a pipe. In order to prevent an occurrence of dangerous stress concentrations in pipes in contact with such clamping rings and to permit such rings to be manufactured economically, the clamping ring is formed on its inside surface with a multiplicity of generally peripherally extending indentations, each of which extends only along part of the periphery of said inside surface, and said indentations are offset from each other in said peripheral directions and adjoint or overlap.
