A coupling apparatus for trucking straps used on flatbed trailer loads intended to hold stacked loads in a more secure manner while eliminating their tendency to shift during transit is herein disclosed. The apparatus provides a connecting link which takes the form of a flattened figure “8” with the approximate dimension of four-and-a-half (4½) inches wide and two-and-a-half (2½) inches tall. The link is used to hold one end of a conventional trucking strap, which is then looped around a load and then back through the other side of the link. The free end is then secured to a stationary object such as a rub bar on the edge of the flatbed trailer using a ratcheting buckle. Thus, the loop around the load is self tightening and automatically tightens in the event of a shifting load as is commonly the case with tubular loads such as PVC pipe, regular pipe, lumber and the like. The apparatus would be used on alternating sides of the load to provide a balanced bi-directional restraint.
