An electrical connector includes a crimpable tubular body including a receiving portion for receiving a wire conductor via an opening at a longitudinal end of the tubular body. The tubular body provides a permanent electrical connection to the wire conductor only upon at least a portion of the tubular body being crimped. The receiving portion has a tapered shape and inward projections for engaging the wire conductor to provide sufficient frictional force to resist removal of the wire conductor from the receiving portion prior to crimping, without providing a permanent electrical connection between the tubular body and the wire conductor. In one implementation, the electrical connector is a butt connector with two such equally sized receiving portions for splicing together two wires. In another implementation, the electrical connector is a butt connector with two different sized receiving portions for splicing together two differently sized wires.
