To provide an end part reinforcement member for a resin barricade pipe, usable easily in assembling by simple structure, capable of preventing effectively the damage caused by excessive pressure of clamp clamping in a barricade.

This end part reinforcement member for the resin barricade pipe is a member for reinforcing an end part 21 of the cylindrical resin pipe 2 with the end part 21 clamped by the clamps C arranged in barricade support legs A, and the end part reinforcement member for the resin barricade pipe is completed by adopting a technical means of forming an outer circumferential face of a cylindrical body part 1 into a tapered shape, of forming a surface of the outer circumferential face with an axial-directional protrusion 11, of inserting a small-diametric end part 12 of the body part 1 into an opening part 21a in the end part 21 of the resin pipe 2, and of tension-fitting the protrusion 11 onto an inner surface 22 of the pipe 2 to constitute double structure.
