A cover (20) has opposed halves (21) with butting walls (28). An engaging projection (27) is formed in an accommodation concavity (30) rearward from an edge (29) of the butting wall (28). A portion between the engaging projection (27) and the edge (29A) on a bottom surface of the accommodation concavity (30) defines a temporary holding surface (32) which is contacted by a connection portion (26B) of a locking arm (26) on the opposed half (21). The temporary holding surface (32) stabilizes the posture of each half (21) before the locking arm (26) rides over the engaging projection (27). Thus, halves (21) do not incline and the connection operation is accomplished smoothly.
