The invention relates to a reinforcement wire clip for live-line operation. The reinforcement wire clip comprises two wire clip bodies, wherein each wire clip body comprises a wire clip seat, a lower part of the wire clip seat is in threaded connection with a bolt, a top end of the bolt is rotatably connected with a fastening element, a side surface of the fastening element is in contact with an inner side surface of the wire clip seat so as to prevent the fastening element from rotating relative to the wire clip seat, the fastening element is matched with an upper part of the wire clip seat to lock or loosen a wire or a line nose or a binding post or a wiring board, the fastening element and the upper part of the wire clip seat are provided with inner concave surfaces which are oppositely arranged, tin (silver)-plated soft copper wires are densely arranged on the surfaces, the surfaces are coated with oxide layer removers, a flexible cable is connected between the two wire clip bodies, and two ends of the flexible cable separately pass through wiring tails of the wire clip seats and then are connected with the tin (silver)-plated soft copper wires. The reinforcement wire clip has the advantages of high reliability and wide application range, and is convenient to install.
