1. A device for capacitively coupling an electrical connection to an insulated wire comprising:

  • a thin semitubular electrical contact adapted to be disposed about the outer surface of the insulated wire, said contact being coupled to the electrical connection for capacitively coupling the electrical connection to the insulated wire;

    a first semicircular insulative member having a first longitudinal groove therein adapted to receive the insulated wire, said first member having a recess which communicates with said groove to receive said semitubular electrical contact;

    a second semicircular insulative member including a second longitudinal groove adapted to receive the insulated wire, said first and second semicircular insulative members adapted to cooperate to substantially completely encase the insulated wire; and

    means for securing said first and second members together, said means including a metal semitubular element to substantially cover said first member to shield the capacitive coupling from outside noises, said means also includes fastening means to contact said second member and bind such to said first member.
