Cannot be connected directly. That is, it is necessary to interpose an intermediate member having a flange surface that can be connected to this flange surface, and then connect this intermediate member and the end of a normal resin pipe with a pipe joint, resulting in a supplementary pipe. As a result, the construction work becomes troublesome and costs increase. Also, in the case where one resin pipe is made of polyethylene and the other resin pipe is made of vinyl chloride, direct fusion cannot be performed and the pipe becomes a supplementary pipe.

Further, a coil 13 that generates heat when energized is embedded in this inner peripheral surface, and the resin around the periphery of the coil 13 is melted by the heat generated by the coil 13. That is, the fused portion 11
By fitting the end portion 20 of the resin tube 2 into the coil 13 and energizing the coil 13, the inner circumferential wall surface of the fused portion 11 and the outer circumferential wall surface of the resin tube are melted and fused. Therefore, the coil 13 is embedded so as to surround the entire fused portion 11, so that a sufficient fused area can be secured by fusion. This coil 13 is wired at its end to a current-carrying terminal 14 protruding from the outer periphery of the fused portion 11, so that it can be powered from the current-carrying terminal 14. Further, an indicator 15 is provided on the outer circumferential surface of the fused portion 11, and the indicator 15 allows the fused state of the periphery of the coil 13 to be grasped.

Then, resin pipes 2 and 3 inserted from both the joint part 12 and the fusion part 11 are provided on the inner circumferential surface of the boundary between the base end of the joint part 12 and the base end of the fusion part 11. A stopper 16 is provided to protrude to prevent penetration.

It is obtained by injecting the molding material under high pressure in the arranged state. In this way, since the product is integrally formed by injection molding, factory production becomes easy. Furthermore, since it is manufactured using a mold, variations in dimensional accuracy are reduced.

The flange socket 18 may be connected to the flange portion 21 . Furthermore, as shown in FIG. 4, the joint portion 12 having the TS socket, the bell socket 17, and the flange socket 18 may be formed into branched parts.
