Abstract

PURPOSE:A thruster inserted in a thermoplastic resin is moved and a sliding block is slid to expand the diameter of a split ring and thus the pipe wall of the socket part outward thereby a groove for setting ring is readily formed on the periphery inside the socket of a thermoplastic resin pipe.
