A locking projection (29) of a housing (10) fits in a temporary locking concavity (65) of a retainer (60) to hold the retainer (60) at a temporary locking position and fits in a main locking concavity (64) to hold the retainer (60) at a main locking position. The main locking concavity (64) has a first slope (67) on a forward surface in a direction in which the retainer (60) is drawn out. The temporary locking concavity (65) has a first locking surface (69) on a forward surface and aligned orthogonal to the direction in which retainer (60) is drawn out. The locking projection (29) has a second slope (35) aligned along a surface of the first slope (67) at the main locking position and has a second locking surface (33) disposed along a surface direction of the first locking surface (69) at the temporary locking position.
