ABSTRACT:
A pipe joint in which a force for retaining a semirigid plastic pipe to a joint body is provided in such a manner that an outward expanded portion of the pipe which is formed by inserting an annular shape-retaining member which does not obstruct the flow of fluid into the pipe is connected to the joint body by a box nut. This pipe joint portion is formed by employing an apparatus having a clamp for temporarily fixing the pipe at one end of a base arm, a grip portion disposed at the other end thereof, a toggle lever pivotally attached to the grip portion, a sliding rod engaging at its one end with an end of the toggle lever and capable of moving to the left and right while being supported by a guide base attached to the base arm. The shape-retaining member is inserted into the pipe by this sliding rod.
