ABSTRACT:
A cover for covering a lock arm is mounted through a self hinge portion on an upper surface of a female housing for pivotal movement between an open and a closed position, and a non-engagement detection projection is formed on a back surface of the cover at a proximal end portion thereof. When the cover is pushed by an operator to be closed, the lock arm slants forwardly upwardly with a hook portion placed on an engagement portion formed on a male housing. If the male and female housings are not engaged with each other, and therefore the non-engagement detection projection abuts against the lock arm, the cover is held in a raised condition thus indicating that the housings are not engaged with each other. Because the cover is mounted integrally on the housing, the number of the component parts is reduced, and extra management of the parts and extra assembling steps are eliminated.
