A connector assembly has a male connector (10) with a receptacle (14), a female connector (60) to be fit into the receptacle (14) and a moving plate (40) for positioning male terminal fittings (20). The moving plate (40) includes a plate-like plate main body (42) with positioning holes 47 and is movable toward a back side of the receptacle (14) together with the female connector (60) from an initial position where leading ends of the male terminal fittings (20) project through the positioning holes (47). Protection walls (41) project forward to protect the leading ends of the male terminal fittings (20) projecting at the initial position. The female connector (60) is formed with recesses (66) for permitting the protection walls (41) to escape. Each protection wall (41) is arranged between adjacent male terminal fitting groups (20).
