Abstract: A device for attachment to an upright post on a bed of a pick-up truck or other vehicle for gripping one end of a tie-down rope to apply tension to the rope to hold pipe or other load on the vehicle when the rope passes over the load and as the opposite end of the rope is secured to the vehicle. The device includes a shiftable, generally upright bar coupled with a jacking unit secured by a bracket to the post. A cam member on the upper end of the bar is used to wedge the rope against the bar after the rope has been passed over the load. Then, by operating the jacking unit, the bar is caused to be lowered, thereby placing tension on the rope and holding the load in a rigid, secure position on the vehicle. The movement of the bar can be reversed to remove the tension by operating the jacking unit in reverse.
