Abstract
A trailer safety chain has a connection link member in the form of either a double S-hook or a single S-hook, the double S-hook cooperating with a unique matching slot for providing enhanced safety securing of the hook to a towing vehicle. A securing bracket for the chain is attached to a vehicle rear and includes two like unique openings which straddle a central tow hitch tongue and coupler ball for receiving two like trailer safety chain hooks. Each opening, which is T-shaped has intersecting slots, which accommodate either of the two hooks of different dimensions, and does so, without diminishing the enhanced locking security of the double S-hook.
