The springless electric gate tensioner receptacle and plug connect and axially adjust relative to each other in order to mechanically tension the electrical fence gate wire. The receptacle has a resilient, electrically non-conductive insulator covering handle and conductive sleeve portions. Spaced apart bayonet slots are disposed axially along diametrically opposite sides of the sleeve. The plug includes a solid cylindrical conductive member extending from a handle, the handle being covered with a resilient, electrically non-conductive insulator. Bayonet lugs extend from the plug near its end and project outwardly in a radial direction approximately 180° from each other. Conducting rings extend from the plug and receptacle handles for connection to the gate and fence wires. The projecting bayonet lugs of the plug twist-lock engage user selectable receptacle slots, thereby tensioning the gate wire.
