In the process of connecting two housings (10, 30), a lock arm (36) is resiliently deformed in an unlocking direction crossing a connecting direction of the two housings (10, 30) by sliding in contact with a guiding surface (17) of a lock portion (16). The guiding surface (17) includes a first guiding surface (17A) arranged in a front area in the connecting direction to the second housing (30) and a second guiding surface (17B) arranged in an area behind the first guiding surface (17A) in the connecting direction to the second housing (30) and having a steep area (22) whose angle of inclination with respect to the connecting direction of the two housings (10, 30) is larger than that of the first guiding surface (17A). |
