This removal tool C is provided with a pair of guide frames 12 and 13 having an inner peripheral shape curved along the outer periphery of the cable main body 4 at the tip of the elongated handle 11. A pair of single-line holding frames 14 and 15 having an inner peripheral shape curved along the outer periphery of the cable body 4 in a direction opposite to the directions 12 and 13 are provided. Is applied. The interval between the pair of guide frames 12 and 13 and the interval between the pair of single-line press frames 14 and 15 are determined by the pre-hanger separation remaining portion 6.
It is set wider than the width of a.
