PROBLEM TO BE SOLVED: To provide a locking means which is superior in workability of pushing a retainer in a lock releasing and a final locking position, while the retainer can be retained in a temporary locking position. SOLUTION: Even if the retainer 30, which is located in a temporary locking position, is pushed to the final locking position side, the retainer is locked in a displacement preventing state to the final locking position, by having a lock piece 41 interface with a receptacle section 43 of a housing 20. When the retainer 30 is stuffed into the final locking position, after releasing the locking, by making the locking piece 41 displace in approximately parallel to an rear end face 33, the locking piece 41 is pushed in a way so that it is pushed against the rear end face 33. Since the direction of the pushing-on of the locking piece 41 is the same direction as the direction which the retainer 30 is stuffed into the final locking position, the retainer 30 can be pushed in easily and surely.
