A method of joining first and second piping materials with a C ring. The C ring has a sharp annular rim along the internal peripheral surface thereof on the pipe end side, and the C ring also has a cross-section such that a first cornered edge formed along the internal peripheral surface of the C ring on the annular gasket side and a second cornered edge formed along the external peripheral surface of the C ring on the pipe end side each define an acute angle. An end portion of the second piping material is inserted into the socket and into the C ring. The piping material are held by means of a pair of clamping jaws each having a tapered plane of clamping action opposing each other, and the jaws are then moved closer to each other along the axis of the pipes, respectively, for pressurizing the piping materials to effect plastic deformation of at least the maximum diameter portion at the end of the first piping material to deform the gasket and clamp the piping materials together. |
