A connector 1 provided with a lock ensuring mechanism includes a female housing 2, a male housing 3, and a lock ensuring member 4. The female housing 2 is provided with a lock hole 5. The male housing 3 is provided with a lock arm 16 having a lock projection 36 which is adapted to be engaged with the lock hole 5. The lock ensuring member 4 is movably supported by the male housing 3. The lock ensuring member 4 has a flexible piece 31 which is in contact with the lock projection 36 in a state where the lock projection 36 is not engaged with the lock hole 5. When the lock projection 36 has come into engagement with the lock hole 5, the flexible piece 31 is detached from the lock projection 36. In this manner, an incompletely engaged state of the housings with each other can be reliably detected.

1. A connector with a lock ensuring mechanism comprising;a female housing for receiving terminals; a male housing for receiving mating terminals; a lock arm formed integrally with an outer wall of either one of said female housing and said male housing, and extended in a longitudinal direction of said terminals received in said housings; a locking part provided in the other of said female housing and said male housing, and adapted to be engaged with said lock arm; and a lock ensuring member including a release preventing part which can be engaged with said lock arm, said lock ensuring member being supported by said one housing so as to move in a longitudinal direction of said terminals between a locked position in which said release preventing part is engaged with said lock arm and an unlocked position in which said release preventing part is released from the engagement with said lock arm, wherein said lock arm includes a lock projection which projects outward and can be engaged with said locking part and said release preventing part, wherein said lock ensuring member includes a lock recess into which said lock projection is adapted to enter when said locking part and said lock projection are engaged with each other, and a flexible piece which can be elastically deformed between a restricted position in which said flexible piece is in contact with said lock projection to restrict movement of said lock ensuring member toward said other housing and a restriction released position in which said flexible piece moves apart from said lock projection narrowing said lock recess and at the same time, allows said lock ensuring member to move toward said other housing, wherein said restricted position is maintained until said lock projection has entered into said lock recess to be engaged with said locking part, and said restriction released position is attained when said lock projection has been engaged with said locking part.
