A high strength electrical connector includes an outer cylindrical, rigid support cover open at both ends and preferably comprised of a high strength metal. A first electrical lead extends through a tension bushing attached to one end of the support cover. A mating receptacle through which a second electrical lead passes is securely attached to a second opposed end of the support cover. Electrical connection between the ends of the first and second electrical leads is established within the support cover. Securely attaching the ends of the first and second electrical leads together within the support cover, which is preferably comprised of a high strength metal, directs axial and transverse forces exerted on the first electrical lead through the support cover, thus bypassing the electrical connection.
