Claims

[Scope of utility model registration request]

In a synthetic resin pipe joint structure in which a synthetic resin pipe and a socket are joined with an adhesive, an annular groove is provided inside the socket, and an annular portion having a curvature such that the outer periphery touches the groove and an annular groove are formed in this groove. A locking body consisting of a plurality of elastic protrusions that are integrally formed inside the socket and whose tips are located inside the inner surface of the socket is attached, and a locking groove that engages with the elastic protrusions is installed on the outside of the tip of the synthetic resin pipe. A joint structure for synthetic resin pipes characterized by the provision of.
