A splice block for interconnecting conductors, which include wire and insulation covering the wire. A container having openings through which conductors can access an interior of the container contains multiple connectors. Each connector includes a housing having a first slot having a width that is less than a width of an outer surface of the insulation and is engageable with the wire of a conductor, and a cover including a second slot having a width that is less than a width of an outer surface of the insulation and engageable with the wire of the conductor, the second slot being spaced along a length of the conductor from the first slot, and offset laterally from the first slot. An electrically conductive connection interconnects adjacent connectors. A container top maintains engagement among the cover, the housing and a connector, such that the first and second slots engage the wire of the conductor.
