Claim:
A connector, comprising: a frame including at least first and second housing accommodating recesses, at least one first engaging portion being formed on an inner surface of the first housing accommodating recess and at least one second engaging portion being formed on an inner surface of the second housing accommodating recess; and at least first and second auxiliary housings shaped to conform respectively with the first and second housing accommodating recesses, at least one first lock being formed on an outer surface of the first auxiliary housing and being engageable with the first engaging portion for holding the first auxiliary housing in the first housing accommodating recess of the frame, at least one second lock being formed on an outer surface of the second auxiliary housing and being engageable with the second engaging portion for holding the second auxiliary housing in the second housing accommodating recess of the frame, the locks or the engaging portions being resiliently deformable arms, each of the arms including a lock hole or recess and the other of the locks and the engaging portions being lock projections, the auxiliary housings being held in the frame by fitting the lock projections into the lock holes or recesses, the first lock being formed so as not to be engageable with the second engaging portion if the first housing is inserted inadvertently into the second housing accommodating recess and the second lock being formed so as not to be engageable with the first engaging portion if the second housing is inserted inadvertently into the first housing accommodating recess, thereby preventing the auxiliary housings from being locked inadvertently in a non-corresponding one of the housing accommodating recesses and ensuring engagement of the locks with the respective engaging portions when the auxiliary housings are inserted correctly into the housing accommodating recesses corresponding thereto.
