求項１に記載の伸縮可撓式管継手。[Claims for Utility Model Registration] (1) A tubular joint body with a thread at one end, an annular packing made of an elastic material installed between the inner peripheral surface of the joint body and the outer peripheral surface of the connected pipe, and the joint body. A telescoping flexible pipe joint comprising a cap nut having an annular recess that is adapted to be tightened onto a screw of a main body, and a tube pull-out prevention means disposed in the annular recess, the tube pull-out prevention means It consists of a retaining ring having a truncated conical cylindrical part vertically divided at one point in the axial direction, and the small diameter side end of the truncated conical cylindrical part is provided with a retaining ring provided on the pipe to be connected. 1. A telescoping flexible pipe joint, comprising: an inwardly projecting annular projection that fits into a circumferential groove; and further comprising means for expanding and contracting the cylindrical portion in the radial direction. (2) The means capable of expanding and contracting in the radial direction is characterized by being constructed by making cuts of a certain length in the cylindrical portion of the retaining ring, extending alternately from both ends in parallel to the axial direction. The telescoping flexible pipe joint according to claim 1.
