A male housing (10) has a lock (17), whereas a female housing (20) has a resiliently deformable lock arm (31) cantilevered along a connecting direction of the two housings (10, 20). The lock arm (31) deforms in the process of connecting the two housings (10, 20) and resiliently restores upon proper connection to engage the lock (17) for holding the housings (10, 20) connected. The female housing (20) has a first lock protecting wall (36) covering a side of the lock arm (31) including a free end portion (31b), and a second lock protecting wall (37) covering a side of the lock arm (31) including base end portions (31a). An unlocking space (38) between the first and second lock protecting wall (36, 37) exposes a middle part (31c) of the lock arm (31) to the outside.
