An electrical connector for connection of pairs of wires to other pairs of wires, said connector comprising:

• a terminal block, said terminal block comprising
• a base having means for supporting a plurality of wires transversely thereof,
• a cover adapted to fit on the base, said cover having a plurality of terminal contacts for making connection to wries supported by the base and for enclosing the ends of the wires in the base, said cover having apertures affording access to said contacts, and said cover having location means about said apertures for polarizing pairs of said apertures;
• and
• a plurality of plugs for making contact with said contacts in said terminal block, said plugs comprising
• an insulative body, said body having opposite ends and a hinged cap supported on one end, a thin metal splicing contact supported in said body with opposite end portions, one end portion of said contact being a tuning fork contact portion adapted to make electrical connection with said terminal contacts and the other end portion being an insulation displacing contact portion adapted to make electrical connection to a jumper wire, said cap having means for facilitating connection between a said jumper wire and said other end portion of said splicing contact, having an aperture therein affording access to said insulation displacing contact portion, and having location means mounted thereon to afford proper location of a second plug on said cap, the other end of said body having means for mating with said location means of said cover for positioning said one end portion of said splicing contact in a said aperture to make electrical contact to said terminal contact.
