PURPOSE: A connecting pipe for a synthetic resin pipe is provided to easily and precisely connect the synthetic resin pipes by forcibly fitting the synthetic resin pipes into both sides of the connecting pipe. CONSTITUTION: Coupling grooves(2,6) are formed at both ends of a connecting pipe(1). A gentle incline is integrally formed with a steep incline in the coupling groove. A heating wire(21) generates heat, and is arranged at regular intervals. A terminal wire(30) is connected to the heating wire, and supplies power to the heating wire. A glue layer is formed at the inside of the coupling groove and the adhesive part of two synthetic resin pipes.
