A divided connector (10) has a housing main body (11) with main cavities (16) and main front walls (17) that define front limit positions for main terminal fittings (15) in the main cavities (16). The housing main body (11) also has an accommodating portion (12) with an accommodating front wall (13) that defines a front limit position for an auxiliary housing (30) in the accommodating portion (12). The auxiliary housing (30) has auxiliary cavities (32) with auxiliary front walls (33) that define front limit positions of auxiliary terminal fittings (31) in the auxiliary cavities (32). A sum of the thicknesses of auxiliary front walls (33) and the accommodating front wall (13) exceeds the thickness of main front walls (17). Thus, the auxiliary terminal fittings (31) are backward from the main-body terminal fittings (15) by this thickness difference and a peak connecting force is reduced.
