250 8B 3 way 2 or 3 wire jelly crimp connectors BT Virgin telephone joiners Clear with red top which are getting hard to find now These crimps can be used to join 0.32mm to 0.9mm copper core telephone wire cable or aluminium core cable up to 0.5mm It can be used internally or externally as the waterproof gel stops the wires from corroding. They are much better than using screw terminal blocks as they do not degrade the broadband signal. They are very simple to use, insert one wire in each hole and just squeeze down using pliers. The wires do not need to be stripped as the IDC connection in the crimp does that for you.
