Abstract
Abstract A pair of connecting pipes each having one end abutting an operative dependent element of a tow bar, and the other end operatively connected to the lower A-frame of a vehicle to thereby maintain the tow bar at a predetermined distance from the vehicle when tension chains are passed through the pipes and connected to the A-frame and tow bar respectively. This arrangement prevents damage to bumpers, underpans and cowlings of automobiles, resulting from previous towing apparatus, due to the tow bar being directly held against a portion of the vehicle.
