Claim 1

A spring locking device for a connector including a female connector member and a male connector member, said spring locking device including two pairs of bearings arranged on both ends of a mounting flange of one connector member, respectively, each of the bearings having openings in directions substantially perpendicular to longitudinal directions of the one connector member and having a semicylindrical inner surface, and locking members made of a springy wire, each locking member having two legs spaced in parallel with each other and two support pins formed by bent outwardly relative to the legs and rotatably supported in said one pair of bearings, thereby locking the two connector members by turning the locking members into slits formed in the other connector member after the two connector members are connected, wherein each of the locking members comprises the legs having lower ends outwardly bent and the support pins continuous to the lower ends and having bent corners between the lower ends and the support pins, and said bent corners are positioned inside of the bearings and in contact with bottoms of the bearings and said support pins are in contact with semicircular edges of the bearings and extend therefrom out of the bearings on sides opposite to those of the legs when the locking members are mounted in the bearings.
