Abstract
A lock assurance mechanism for a connector having a pair of housings. A lock assurance member is attached to one housing having a lock arm in such a manner that the lock assurance member is movable back and forth relative to the housing, the lock assurance member having a flexible retaining lever with a retaining pin at a free end thereof. A guide wall having a guide holder for supporting the retaining pin is formed upright on the housing. A back-and-forth movement limitation piece for limiting back and forth movement of the retaining pin is provided on the other housing. When the housings are fitted together to engage the lock arm with a lock retaining portion, the retaining pin abutted against the back-and-forth movement limitation piece is disengaged from the guide holder to allow the displacement of the flexible retaining lever; and subsequently by moving the lock assurance member, the retaining pin is brought into engagement with a rear surface of the back-and-forth movement limitation piece, thereby completely retaining the flexible retaining lever relative to the former housing.
