Abstract: An electric connector is comprised of: a housing; a clamper for clamping a multicore cable formed with a plurality of sheathed cable elements bound by an outer jacket, a predetermined length of the outer jacket at an end thereof being removed; and a contact holder accommodated and held in the housing, a portion of the contact holder projecting from the housing being adapted to be inserted into a mating connector. The clamper includes a clamper body for clamping the outer jacket and a wing-like portion projecting radially from the clamper body. Contacts are fitted in the contact holder in such a manner as to be respectively connected to tips of core wires which are exposed with portions of respective sheaths of the plurality of sheathed cable elements removed.
