A connector for electrically and mechanically connecting insulated conductor wires encapsulated in protective tubing. Embodiments of the connector provide a protective outer sheathing that circumscribes the conductive and insulating structures within the connector. The connector is formed with a plurality of tubular fitting assemblies for securely attaching the connector to down hole electrical power cables. The connector is also formed with an internal insulating boot having an internal passage adapted to surround the conductive elements of the connector to provide a reliable down hole electrical connector.
