接続することができる。In the electrofusion joint clamping apparatus of the present invention thus constructed, the angles of the two supports 1 and 1 are fixed by the knob-equipped screw 4 according to the shape of the electrofusion joint E, and the electrofusion is performed. Set on the upper surface of the joint E. As shown, terminals 15 and the like for energization protrude from the upper surface of the electrofusion joint E, and these can be accommodated between two parallel support rods 3 of the support 1. Moreover, as shown in FIG. 1, since the support rod 3 is located higher than the seating surface 6 of the main body 5,
There is no interference with the support 1. In addition, an electric wire or the like for energization can be connected to the terminal 15 using the space between the support rods 3.

By sliding on the support rod 3, there is an advantage that it is possible to cope with the electrofusion joints E of various shapes and sizes. In addition, since it can be used by being set on the upper surfaces of the electrofusion joint E and the resin pipe P, it is sufficient to dig a hole through which the chain 12 can pass.
It is not necessary to dig a deep pit below the resin pipe P to be joined as in the related art. Therefore, the present invention is highly valuable as a clamp device for an electrofusion joint that solves the conventional problems.
