Claims

[Scope of Claim for Utility Model Registration] (1) A joint body in which an annular groove is formed in the large diameter hole on the inlet side, a gasket groove is formed in the small diameter hole on the back side, and a gasket is attached, and a joint body that is inserted into the joint body. , has a tapered inner surface that becomes slightly larger in diameter toward the inlet side, has a concave groove that expands in the radial direction on the inlet side of the tapered inner surface, and has a side wall on the inlet side of the concave groove facing the inlet side. a thin annular retainer formed on an inclined surface with a small diameter; a retainer holder that holds the retainer and has an annular groove formed on its outer peripheral surface; and a retainer holder that is installed between the annular grooves of the retainer holder and the joint body. a retaining ring formed retractably by a notch in the axial direction; a rubber ring installed in the concave groove of the retainer; and a retaining ring installed between the inclined surface of the retainer and the inner surface of the rubber ring, a stop ring that can be elastically deformed; a rubber gasket that is attached to the outer surface of the end of the corrugated tube to be connected, has a corrugated inner surface that fits into the corrugated tube, and has an outer surface that fits into the tapered inner surface of the retainer; A corrugated pipe insertion type pipe joint comprising a stiffener attached to the inner surface of the end of the corrugated pipe. (2) Utility Model Registration In the corrugated pipe insertion type pipe joint according to claim 1, a nut is screwed onto the inner surface of the rear end of the retainer holder, and the retainer holder is attached to the end of the nut on the retainer holder side. 1. A corrugated tube plug-in type pipe joint, characterized in that an inclined surface is formed that narrows toward the side, and a second stop ring that engages with a trough on the outer surface of the corrugated tube is attached to the inclined surface.
