DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. First, a stainless steel wire core 1 is coated with a vinyl chloride coating 2 and a coating 4 at the end of a cord 3 is stripped. After exposing the end portion 5 (see FIG. 1), the end portion 5 is folded in half, the half 6 of the end portion is overlapped with the other half 7, and a brass retaining sleeve 8 is fitted in the middle of the overlapped portion. Covering (see FIG. 2), the retaining sleeve 8 is crimped (see FIG. 3) to bind it, and the excess part 9 formed by this binding is cut off (see FIG. 3) to constitute a retaining aid wheel 10. Then, the portion near the exposed end 5 of the non-strip portion 11 of the coating 2 of the cord 3 is folded in two, and the exposed end 5 is overlapped with the non-strip portion 11 (see FIG. 4). The fastening sleeve 13 The retaining assisting wheel 10, the retaining sleeve 8, and the end of the non-strip portion 11 are covered (see FIGS. 4 and 5) so that the ends of the non-strip portion 11 are hidden therein, and the fixing sleeve 13 is crimped (see FIG. 5). The crimping portion 14 of the fastening sleeve 13 is covered with a heat-shrinkable synthetic resin tube 15 (see FIGS. 5 and 6) and is thermally contracted to cover the entire crimping portion 14 (see FIGS. 6 and 7). Therefore, the connecting ring 16 is formed at the end of the cord 3.
