To provide a clamp device and an auxiliary member for a clamp device which spoils no quality of junction of an electrofusion joint even when piping work is performed before the completion of fusion, enables a prompt execution because of the conduct of the piping work prior to the completion of fusion, and scratches no surface of a resin tube.
A clamp member 15La and a clamp member 15Ra are provided to a plinth 14 adjacent to the electrofusion joint 12 of the clamp device in a state that the resin tube 11L and the resin tube 11R remains inserted in an insertion hole 12La and an insertion hole 12Ra respectively. The insertion hole 12La and the insertion hole 12Ra are provided to both ends of the electrofusion joint 12, and the clamp member 15La and the clamp member 15Ra are used for fixing an insertion end 11La and an insertion end 11Ra respectively. A clamp member 15Lb and a clamp member 15Rb are provided side by side on the side which is far from the clamp member 15La and the clamp member 15Ra respectively with respect to the insertion hole 12La and the insertion hole 12Ra in order to prevent the insertion end 11La and the insertion end 11Ra from moving when an external force is exerted on the resin tubes 11L, 11R.
