고정되어서 결합된 T형 EF조인트(1)는 열가소성수지관(2)의 단부에 소켓부분(3)을 보유한다. 한쌍의 연결핀(4)은 각각의 소켓부위의 끝표면에서 바깥쪽으로 튀어나와 있다. 제어선(7)은 선단에 연결기(6)에 맞물린 연결핀(4)이 있는 제어장치로부터 뻗어 있다. 제어장치(5)는 시작스위치와 정지스위치(11), 그리고 표시기(12)를 구비하였다. 관(2)은 소켓부위(3) 각각에 고정되어 있고, 각각의 EF조인트의 소켓부분(3)은 내주면에 독립된 전열선(13)이 매입되어 있다.The fixed and joined T-shaped EF joint 1 has a socket portion 3 at the end of the thermoplastic resin tube 2. A pair of connecting pins 4 protrude outward from the end surface of each socket portion. The control line 7 extends from the control device with a connecting pin 4 engaged with the connector 6 at the tip. The control device 5 has a start switch, a stop switch 11, and an indicator 12. The pipe 2 is fixed to each of the socket portions 3, and an independent heating wire 13 is embedded in the inner peripheral surface of the socket portion 3 of each EF joint.
