A separable electrical connector for a plurality of axially connectable cylindrical electrical terminals adapted for coupling to the threads of insulated wires and having an annular external recess on each of the terminals. The connector include an elongated, rigid, nonconductive, generally tubular member having a plurality of apertures extending axially therethrough and a plurality of outboard ramping retention abutments formed integrally with the tubular member upon at least one inner surface of a radially outboard portion of the tubular member. A plurality of axially extending terminal guide fingers is included upon a central land located within the tubular member. A spacer engages with the central land for displacing the terminal guide fingers in the direction of the ramping retention abutments so that the terminals will be retained securely within the connector assembly.
