  • at least two arrangement grooves formed in an outer surface of the holder to define a portion of the path and to extend substantially from the rear end of the holder to the fold, the detection wire being fitted in the arrangement grooves, the restricting means comprising a rib projecting at the rear end of the holder in a position to partition two extending portions of the detecting wire extending respectively from the arrangement groove, and a restricting means for preventing the detection wire from coming out of the arrangement grooves.
