<p>An object of the present invention is to prevent a wire from getting jammed. A connector housing 20 is formed with a resiliently deformable lock arm 25, and a pair of ribs 36 are formed to stand at the opposite sides of the lock arm 25. The lock arm 25 resiliently locks a mating connector housing to lock the two connector housings in their connected state. A pair of projecting portions 35 are formed at the opposite lateral edges of the lock arm 25 to project toward the opposite lateral sides. Between the projecting portions 35 and the ribs 36, clearances Q bent to have channel shapes in rear view are formed by recessing the inner surfaces of the ribs 36.</p>
