Disclosed herein is a length adjustment device of a lamp connection wire, which can easily and simply adjust the length of the lamp connection wire that connects a warming lamp to a power cutoff unit in a livestock barn. The length adjustment device has semicircular parts which are respectively provided on opposite ends of the length adjustment device, with a wire hole being formed through the center of each of the semicircular parts and allowing the lamp connection wire to pass through the wire hole. The semicircular parts are integrated into a single body by bridges, with a space defined between the bridges. In the length adjustment device, each of the bridges is integrally provided with a reinforcing ridge. Furthermore, each of the bridges is provided with at least one open circular hole at a position around the reinforcing ridge so that a power output cable, electrically connected to both the power cutoff unit and the warming lamp, can be tied to the length adjustment device. Because a farmer can easily and simply adjust the length of the lamp connection wire using the length adjustment device, the length adjustment device enhances work efficiency and saves labor while adjusting the heights of the lamps and prevents the power output cable from sagging or twisting.
