Abstract
In a pipe coupling for connecting pipes as fluid conduits, a split clamping ring, which is of arcuated configuration in cross section, has a pair of spaced circular sharp edges directed toward the pipe for firm engagement therewith and is disposed in an annular groove formed internally of a body so as to be slightly displaceable relatively to the groove in an axial direction of the body when a certain axial force is applied to the pipe; a deformable sealing ring is disposed in another annular groove formed internally of the body; and a plurality of depressing members are provided for adjustably compressing the clamping ring diametrically.
