Abstract
A retainer inserted from one side face of a housing is equipped with projections which penetrate from the side of hooked grooves of female terminal fittings, and insert portions which penetrate into bending spaces of lances from the side. When female terminal fittings are partially inserted into chambers of the housing, the insert portions of the retainer contact against the side faces of lances which are bent into the bending spaces, and the projections contact against the side face of connecting parts of the female terminal fittings. Further movement of the retainer is prevented and the partial insertion is detected. When the retainer is properly inserted, the projections are fit on the hooked grooves to be directly locked, and the insert portions are inserted in the bending spaces to prevent bending of the lances to be indirectly locked. Therefore, the female terminal fittings are triply and strongly locked, including the hooking of the barb parts of the terminal fittings by the lances. Thus, the reliability of detection of partial insertion of terminal fittings is increased.
