Claims

[Scope of utility model registration request]

A small-diameter tube that has an annular recess on its outer circumferential surface and fits inside the elastic tube, a stopper section that abuts the tip of the elastic tube, and a threaded section on its outer circumferential surface and a sloped surface at the tip of the elastic tube. a pipe joint body having a large diameter tube integrally formed at the same end portion, and a fastening device having an inclined surface opposite to an inclined surface of the large diameter tube and screwed into a threaded portion of the large diameter tube. a nut, and an annular convex portion on the inner circumferential surface thereof, which has inclined surfaces at both ends that slide against the tightening nut and the inclined surfaces of the large diameter cylinder, and whose width dimension in the axial direction is smaller than the annular turning portion. Fitted onto the outer periphery of the elastic tube, the tightening nut is screwed into the threaded portion of the large-diameter tube, and the diameter of the elastic tube is reduced by the centripetal pressing force applied to the inclined surfaces at both ends. 1. A pipe joint for an elastic pipe, comprising: a split ring for pushing a portion into the annular recess.
