A dual conductor wristband utilizing a two-wire tether having a modified phono-type plug. The wristband includes a strap and a connector case, the case having a female jack for receiving the dual connector plug. The plug diameter is smaller than conventional plugs, and the diameter of the pilot hole for the plug tip is correspondingly smaller to prevent accidental connection to a non-grounding tether. Two alternative embodiments are presented for coupling the dual connector plug to two electrically isolated backplates on the connector case. Each backplate is connected to one of the two conductive pathways on the strap.
