Abstract
A pipe coupling comprising a housing which can be clamped about pipe ends which are to be interconnected, and within which housing there is enclosed an inwardly open sealing gasket possessing a substantially C-shaped axial cross-sectional configuration, and both ends of which are supported upon the outer jacket surface of a respective substantially truncated cone-shaped clamping ring, each of which is retained at its outer periphery in the axial direction within the housing and is provided with claws which engage with the periphery of the pipe ends. The clamping rings are clamped in the housing at the region of their larger diameter by means of a fixture or socket engaging both at their outer as well as their inner jacket surface.
