Claim:
A connector comprising: a plurality of sub-connectors, each of the sub-connectors having a rib, the ribs being at different positions on each of the sub-connectors; a housing having a plurality of accommodation concavities into which said sub-connectors can be inserted respectively, grooves communicating respectively with the accommodation concavities, the grooves being disposed to receive the ribs; and a wire cover mounted on the housing and covering electric wires pulled out of the housing, the wire cover having a projected strip projected toward the housing, the projected strip being inserted into the groove side by side with the rib when the sub-connector is accommodated correctly in the accommodation concavity so that the wire cover is prevented from being opened, and the projected strip interferes with the rib in the groove when the sub-connector is accommodated incorrectly in the accommodation concavity to prevent mounting the electric wire cover on the housing.
