Claims

[Scope of utility model registration request]

A cylindrical backing is fitted into a pipe socket provided with an annular bulging groove, and an annular plate is formed by bending inward at the back end of the backing, and this annular plate is fitted into the pipe socket. On the inside of the protrusion of the backing that is applied to the diameter-reducing step at the back and that fits into the annular bulging groove, there is a tapered fold that becomes smaller in diameter than the outside diameter of the connecting pipe toward the back end. A pipe connection section in which a piece is formed and a connection pipe opening is inserted into the pipe socket.
