ABSTRACT The invention concerns twist on wire connectors for electrically connecting ends of wires. A cap is provided in combination with an expansion spring for gripping the wires, the cap having thin walls and external ribs providing the walls with rigidity and a gripping surface. Within the cap is a hollowed out region to allow the spring space to expand. Preferably the spring is of slightly concave shape in an axial direction ie. it is waisted. The new connector caps permit the economic use of expansion springs and permit a greater range of wire sizes and number of wires to be gripped by a connector.
