Claims

[Claims for Utility Model Registration] A small-diameter cylindrical portion into which a rod inserted into and removed from the pipe material is inserted is integrally provided with a large-diameter cylindrical portion attached to the end of the pipe material, The small-diameter cylindrical portion is provided with a circumferentially extending tongue piece formed by cutting out a part of the cylinder wall in a U-shape, and the outer surface of the tongue piece is located at the base of the tongue piece. A joint body made of synthetic resin, which has a smooth curved surface that becomes farther away from the center of the cylindrical portion with a smaller diameter at a point farther from the end, and has recessed stepped portions on both sides of the tongue piece. A protrusion is provided on the inner surface of the cylindrical part externally fitted to the small diameter cylindrical part, and is engaged with the stepped part in the axial direction of the small diameter cylindrical part. and the center of the cylindrical portion are shorter than the distance between the outer surface of the distal end of the tongue and the center of the small diameter cylindrical portion, and the outer surface of the proximal end of the tongue and a socket that is set longer than the distance between the centers of the small diameter cylindrical parts.
