Abstract
Abstract A barrier block is disclosed which incorporates an electrical terminal in the form of a hollow cylindrical barrel provided with a longitudinal slot divided into one or more pairs of wire gripping jaws. The barrel is integral with a second electrical contact seatec on a web which interconnects a pair of partition walls. Opposite ends of the barrier block are molded with intermateable channels allowing a plurality of barrier blocks to be intermated and latched together.
