Abstract: An electrical connector for forming an electrical connection with wires and particularly insulated wires. The connector comprises a connector element having first and second portions (2) with a slot for accepting a wire therebetween. In a preferred embodiment of the invention, the first and second portions are substantially perpendicular and present a stepped slot to a wire that is inserted. The angle between the wire and the first or second portions is in the range 5.degree. to 85.degree. and is typically 45.degree.. When an insulated wire is inserted into the slot, the insulation (8) is penetrated to enable the connector element to establish electrical contact with the conductor (6) of the wire.
