This invention is directed to electrical connectors for joining components of high voltage electrical systems such as splices and elbows for joining high voltage cables and high voltage cables to transformers and the like. Each connector has at least one extendable conductor to which a high voltage cable may be coupled outside of the housing and then returned to the protection of the housing. Typically the elbow has one while the splice has two extendable conductors. Removable fasteners may be used to hold the extendable conductors out of or adjacent the housing ends and lockable fasteners hold the completed joints within the housing.
