Abstract
A chain fastening assembly includes a fastener that has a first loop and a second loop. The first loop has a clevis that is attached to a chain being releasably fastened to the first loop. Additionally, the first loop has a diameter that is sufficient to have a chain link passed therethrough regardless of the orientation of the chain link. The second loop has an inside diameter being sufficient to have a chain link passed therethrough when the chain link is oriented to lie on a vertical plane. Thus, the chain link can be passed into the second loop. Moreover, the second loop has an inside diameter being insufficient to allow the chain link to pass therethrough when the chain link is oriented to lie on a horizontal plane. In this way the fastener retains the chain in a closed loop for towing or the like.
