• the housing includes a member housing section configured to house the fitting detection member, a lock section locked to or detached from the locked section of the mating housing, and a flexible lock arm having locking release sections each of which is configured to slide along an inclined section of the fitting detection member and to release a locked state of the lock section and the locked section,
• the fitting detection member includes a locked portion locked to or detached from the lock section of the flexible lock arm, and a flexible arm section provided with a slip-off prevention locking section locked to or detached from a locking protrusion of the member housing section, and
• when fitting of the mating housing and the housing is released, the flexible arm section is bent and deformed in a direction in which a locking margin between the locking protrusion of the member housing section and the slip-off prevention locking section of the flexible arm section increases.
