Description of the Related Art For gas piping, water supply and sewerage piping, it is important in the laying work that the sealing property of the connecting portion between the pipes, that is, the pipes are connected so that there is no gas leakage or water leakage. Is. However, if you try to connect a synthetic resin pipe by welding through a welding joint (electrofusing joint) with a heater wire embedded inside, the synthetic resin joint or synthetic resin pipe will have a caliber or size. Since the resin thickness varies depending on the manufacturer, the characteristics of the resin vary from manufacturer to manufacturer, and the characteristics of the resin vary from lot to lot, the optimum welding conditions vary depending on the size, lot, or manufacturer.
【０００３】そこで、常に、最適の条件で誰にでも簡単

構成されている。The joint body 2a is made of synthetic resin, has a heater wire (not shown) embedded therein, and has terminals 21 and 21 of the heater wire protruding from the surface. The information code display member 3a is a fixed portion 3 formed of an annular rubber elastic body having a diameter smaller than the outer diameter of the terminal 21.
1, a display portion (tag) 32 on which a bar code 4 which is an information code is displayed, and the same material as that of the fixed portion 31,
It is composed of a connecting portion 33 that connects the fixed portion 31 and the display portion 32.
【００１５】そして、情報コード表示部材３ａは、固定

２が非固定状態になっている。Then, the information code display member 3a fits the fixing portion 31 to the terminal 21 while expanding the diameter of the fixing portion 31,
Since the fixing portion 31 is fixed to the terminal 21 by the elastic contraction force of the rubber elastic body forming the fixing portion 31, the joint body 2
It is integrated with a. That is, in the information code display member 3 a, only the fixing portion 31 is fixed to the joint body 2 a and the display portion 3 connected to the fixing portion 31 via the connecting portion 33.
2 is not fixed.
