INVENTOR: IMMANUEL STRAUB INVENTION: PIPE COUPLING ABSTRACT OF THE DISCLOSURE A pipe coupling comprising a housing which can be clamped about pipe ends which are to be interconnected possesses radially inwardly flexed end flanges. The housing encloses an inwardly open sealing gasket having a substantially C-shaped axial cross-sectional configuration made from an elastomeric material such as synthetic rubber. Both ends of this sealing gasket are supported upon the inner or confronting jacket surface of a respective truncated cone-shaped clamping ring. These clamping rings are supported in the housing at the region of their outer edge or outer region by means of the end flanges. The inner edge or inner region of these clamping rings is structured to mechanically engage or dig into the surface of the pipe ends during clamping of the housing. The inner edge or inner region of the clamping rings possesses a concave profile in order to reduce, on the one hand, the necessary force required during clamping of the housing for digging the inner edge or inner region into the pipe ends and, on the other hand, to clearly limit the depth to which the inner edge or inner region penetrates into the pipe ends.
