PURPOSE: To eliminate the dislocation of a snap retainer from a socket by having the connecting relation of constraining and holding the snap retainer to the socket, between a fastener connected to the socket and the protruding part of the snap retainer from the socket. CONSTITUTION: When a snap retainer 3 is set to a socket 2, the engaging part 3a of the snap retainer 3 is positioned in the slit of the socket 2, and the constricted part 3c and slip-off preventing part 3b of the snap retainer 3 are disposed protruding outside, so that the snap retainer 3 is regulated in the vertical movement by the slit. When a fastener 4 is put on the socket 2, the engaging part 3a of the snap retainer 3 is surrounded by the fastener 4. Accordingly, even if the snap retainer 3 is pulled, the engaging part 3a collides with the inner wall of the fastener 4, and the position is unchanged. The snap retainer 3 is therefore held without the large dislocation of the engaging part 3a from the center of the socket 2. |
