A screw on electrical connector, commonly called a "pigtail," of a type which is generally made up of a tubular insulating cap closed at one end and open at the other end and a tapered helically wound resilient wire coil or spring nested and anchored in the cap, which is constructed and arranged to be screwed down on the stripped ends of two or more wires, and having one or more longitudinally extending levers, each of which is outwardly pivotally connected at one end thereof to the cap at or near the open end thereof. The levers are "L" shaped, each having an axially extending inwardly directed foot at one end thereof, and these feet are axially slidably connected to the cap at the closed end thereof. The cap may contain one or more inwardly directed recesses or channels, each keyed to a respective lever, so shaped and so disposed as to receive its respective lever. The levers may be outwardly pivotally connected to the cap by a resilient plastic means. A method of making such a pigtail connector whereby the cap and lever or levers are cast in one piece, the area of joinder being a resilient plastic material. Each lever is pivoted, along the line of joinder with the cap, toward the closed end of the cap, and the foot end of each lever is axially slidably connected to the closed end of the cap.
