Since the electric wire bending portions 69, 79, 89 need to hold the sub-housings 60, 70 in a normally laminated state against the reaction force of the electric wire 20, a strong holding force is required. Therefore, in addition to the locking by the rear locking portions 78B and 88B, the locking by the rear collective locking portions 88C is used in combination to obtain a strong holding force. Therefore, the separation of the sub-housings 60 and 70 can be effectively suppressed.
