止するものである。 In FIG. 2, a known example of a coupling device (see Japanese Utility Model Application Publication No. 149116/1983) provided with the above-mentioned detachment prevention means is shown, in which the clip main body 16 is formed on one member 12 on the lower surface of the base 9. A fitting part 10 is inserted and fitted into the insertion hole 12a, and a pair of clamping parts 11, 11 for clamping the other member (not shown) are provided on the upper surface of the base 9, respectively.
The inner walls of the clamping parts 11, 11 are provided with engaging grooves 11d, 1 corresponding to the positioning grooves formed in the other member.
1d is formed. A lid body 18 is provided at the upper end of one clamping part 11 of the clip body 16 via a thin wall part 17, and a protrusion 19 facing outward is provided at the upper end of the other clamping part 11. The lid body 18 is rotated around the thin wall portion 17 as a fulcrum.
By engaging the attachment hole 18a formed in the protrusion 19, the clamping parts 11, 11 are pulled inward,
This is to prevent the other member from coming off from the clip body 16.

上昇を招くという欠点があつた。 However, when the attachment hole 18a of the lid body 18 is engaged with the protrusion 19, the lid body 18 is connected to the clip body 16 via the thin part 17, so that
There is a risk that stress will be concentrated on the thin wall portion 17 and it will break. If the thin wall portion 17 is cut, it is necessary to replace it with the clip body 16 or the like. Furthermore, since the clip body 16 and the lid body 18 are connected together through the thin wall portion 17, it is difficult to integrally mold them. It becomes bothersome. In order to avoid stress concentration in the thin portion 17, one of the clamping portions 11 and the lid 18 are
As shown by the two-dot chain lines, the engaging step portions 2
It is also known to provide 0,20. However, even if the engaging step portions 20, 20 are provided in this way, since an external force is applied to the thin wall portion 17 when positioning the other member, the fear of cutting the thin wall portion 17 is not eliminated, and the shape of the thin wall portion 17 is not eliminated. This has the disadvantage that molding becomes more difficult and the price increases.
