PROBLEM TO BE SOLVED: To provide a simply constituted pipe-joint by which pipes can be securely jointed without causing a leakage of high-pressure fluid, even being employed in a joint in piping and vessels for supercritical high-pressure fluids, and the like. SOLUTION: The pipe-jointing member comprises a first joint member 1 to be combined with a pipe A, and a second joint member 2 to be combined with a pipe B. In the second joint member 2, a plurality of engagement projections 12 are formed at intervals in the peripheral direction on the outer periphery of a second joint pipe 9 to be combined with the pipe B. The first joint member 1 is formed to have the inside measurements adequate for holding the engagement projections 12 to keep the second joint pipe 9 insertable through the end. An end plate 8 is formed combinedly at the end of the first joint member 1. In the end plate 8, a hole 8a and a plurality of openings 13 are made. In the hole 8a, the engagement projections 12 are not allowed to pass through, and in the plurality of openings 13, the engagement projections 12 are allowed to pass through. The end-plate inner walls positioned between the openings 13 constitute engagement faces 8b for the engagement projections. COPYRIGHT: (C)2008,JPO&INPIT
