いる。FIG. 1 is an enlarged sectional view of the engaging hook 4 portion.
As shown in 0, the engaging hook 4 is crimped to the end portion of the wire rope 2 and the integrated crimping piece 6 and the end piece 7 are inserted. The end piece 7 is a retainer such as a circlip 8. It is prevented from coming off from the engaging hook 4.

When a force F2 for pulling out 8 is applied, the cylindrical portion insertion port 2
The inner diameter D5 of 2 and the outer diameter D6 of the end piece 18 are the average diameter D of the circlip 19 locked in the locking groove 26.
Since the diameter is smaller than 7, the force F3 in the expansion direction indicated by the arrow is generated in the circlip 19 to prevent the circlip 19 from being reduced in diameter. That is, it is possible to reliably prevent the end piece 18 from coming off.

る。As described above, according to the locking device of the present invention, in the locking device which inserts the insertion member into the inserted member and integrates it to prevent the insertion member from being pulled out, the locking member is provided on the outer peripheral surface of the insertion member. Is formed with a clip groove in which a circlip is fitted in the circumferential direction, and a projection having a diameter larger than the free mean diameter of the circlip is provided in a direction opposite to the insertion direction of the insertion member from the clip groove, while the inserted member is inserted. Since the engaging recessed portion into which the above-mentioned protrusion can be fitted is formed in the insertion opening portion, the insertion member can be easily inserted into the insertion target member without using a tool or the like.
