A fall restrict device for use by a lineworker on a wood electric utility pole includes a flexible strap that can be formed into a loop around the pole. A free end of the strap loop is fastened to a body harness worn by the worker. A pair of pole piercing assembly are secured to the strap, each assembly including a planar plastic paddle formed with slots through which the strap is interleaved. The paddles are positioned so as to locate on diametrically opposite sides of the pole when the loop is formed around the pole, and each paddle carries piercing elements oriented to penetrate the pole as the loop is tightened. Tension on the free strap end automatically causes the piercing elements to penetrate the pole. To permit the device to be released from the pole, each paddle defines a fulcrum to one side of its piercing elements that bears against the pole, and a lever to an opposite side of the piercing elements. The paddles can be manually rotated by means of their levers to pry their piercing elements from the pole.
