    • PROBLEM TO BE SOLVED: To prevent the deformation of a joint by a heat, by forming a thermoplastic resin layer contacting to the inner side of a joint main body, providing a heating wire at the inner side, the outer surface, or the inner surface of the thermoplastic resin layer, and furthermore, providing a connected body inserting groove and a connected body supporting layer. SOLUTION: To the connected body inserting grooves 7 at both ends of a joint 1, the ends of the connected body of a polyolefin tube and the like are inserted, and the connected bodies 5 and 6 are installed in order to contact a nonbridged polyolefin layer 3 to the contacted bodies 5 and 6, and to be supported by a connected body supporting layer 8. When the current is carried to a heating wire 4 under such a condition, the nonbridges polyolefin layer 3 is melted, and fused to the surface layers of the connected bodies 5 and 6 to be integrated and the connected bodies are connected. The connected bodies 5 and 6 which consist of a thermoplastic resin are softened following the melting of the nonbridged polyolefin layer 3 in the fusing, but since the inner surface of the connected bodies 5 and 6 are supported by the connected body supporting layer 8, no deformation is generated. Consequently, the flow passage of the connected bodies 5 and 6 is never narrowed, and a flow passage same as that before the connection can be maintained.
