A connector includes a body having an interior space for receiving de-twisted wires of a cable therein. The body has a plurality of channels for the insertion of the wires. The channels have openings formed on a front end face of the body so as to allow a portion of the wires to expose outside the front end face of the body to be pulled by an operator's hand to the desired position. The body also has a plurality of slots each receiving a metal contact therein. The metal contacts have piercing ends to penetrate into the wires for holding them in position. The exposed portions of wires are then cut off after being held by the metal contacts and a retainer for retaining the connector to a counterpart connector is removably attached to the body. The body has an open bottom defined by two opposite side walls, each having a reduced height defined by an arc connecting segment so as to allow the operator's finger to insert therein for temporarily holding the wires in position. The body also has a strip defined by an elongated opening formed thereon to allow a grounding wire of the cable to surround thereon.
