An electrical connector has first and second connector bodies. The first connector body has an inclined surface and the second connector body has arms that correspond to the inclined surfaces. At the end of the inclined surfaces are generally flat portions forming a ledge that prevent the connector bodies from separating. To unmate the connector bodies, one connector body is rotated relative to the other, causing the arms to move from the generally flat portion to the outer surface of the second connector to allow them to be moved axially away from one another.
