When the joint surface (fusion surface) with 2b is hardened, the locking pin 42
The engagement state between the engagement member 40 and the engagement member 40, and the clamp 16a
And 16b are opened and the pipe fuser 10 is removed. In this fusion step, since the joint 14 and the pipes 12a and 12b are simultaneously fixed by the clamps 16a and 16b, the positions of the pipes 12a and 12b do not shift with respect to the joint 14, and therefore, defective joining can be prevented. . Further, if the clamps 16a and 16b are cooled in advance, the joint surface can be efficiently cooled, and thus the curing time of the joint surface can be shortened.

できるので、それによっても施工性を向上できる。According to this embodiment, since it is not necessary to separately prepare the clamp member and the controller (power supply device) as in the conventional case, the entire device can be downsized and the workability can be improved. Also, the clamps 16a and 16b
The joint terminal 14 and the pipes 12a and 12b can be clamped at the same time and the connection terminal 32 can be connected to the heater terminal 24 at the same time, and the clamping process and the energizing process can be performed by a series of operations, which also improves the workability.

In the above-described embodiment, the connection terminal 32 is provided on the first clamp 16a and the housing 44 is provided on the first arm 18a, but instead of this, the connection terminal 32 is provided on the second clamp 16b.
