に当たって弾性板部１３が不用意に抜け落ちない。In addition to the above embodiment, the following constructions (a) to (e) may be adopted. (A) The second embodiment shown in FIGS. 7 and 8 is a modification of the first embodiment in which the elastic plate portion 13 and the front engagement hole 18 are changed. To form the front side retaining hole 14 and the engaging hole 18
A retaining projection 30 is formed on the right side surface 29 side toward the left side surface 28. The retaining projection 30 faces the retaining hole 14 during the connection. Therefore, even if the elastic plate portion 13 is inadvertently bent and the retaining projection 24 of the rear engaging hole 19 comes off from the rear retaining hole 15 of the elastic plate portion 13, the elastic plate portion 13 is fixed. The end side moves to the front side retaining hole 14 side, the retaining projection 30 is engaged with the retaining hole 14, and the locking surfaces 14b, 30b abut against each other, so that the elastic plate portion 13 does not come off accidentally.
