PURPOSE:To provide a connecting device for a pipe joint with a built-in enclosing electric heating wire by which a piping construction can be carried out easily and reliably. CONSTITUTION:An electric heating wire 12 is buried in a spiral shape at prescribed intervals on the inner peripheral surface of a socket 11 arranged in one end part of a pipe joint 1, and the end part of a synthetic resin pipe 2 is inserted into the socket 11. A locking member 3a is interposed between the inner peripheral surface of the socket 11 and the outer peripheral surface in the end part of the synthetic resin pipe 2, and the slipping-out of the synthetic resin pipe 2 is prevented, and the electric heating wire 12 is made hot, and the inner peripheral surface of the socket 11 and the outer peripheral surface in the end part of the synthetic pipe 2 are fused and joined together. Thereby, a piping construction can be carried out easily, and these can be also fused and joined together reliably/firmly without slipping out of the synthetic resin pipe from the socket 11 of the pipe joint. |
