The strap is arranged to be releasably connected to the worker to form a loop encircling the pole. Each of the gripping units comprises an elongated, arcuate tubular member having a handgrip at one end and pole penetrating members at the other end. The strap extends through both tubular members. The penetrating members are made up of an enlarged head having a plurality of larger upper teeth and a plurality of small lower teeth. Each tooth has a horizontally disposed cutting edge. The gripping units are arranged to be manipulated by the worker grasping the handgrips to cause the cutting edges of all of the teeth to penetrate into the material of the pole.
