ABSTRACT:
An improved towing hook structure including a hook body having a surface provided with reinforcing ribs. The exterior of the hook body is wrapped in a layer of tough and wear-resistant rubber or plastic material using hot pressing to reduce possible damage to or scratching of the surface of a car to be towed. A rubber or plastic stop element and a rubber of plastic projection are integrally formed in the process of hot pressing to extend respectively from both ends of an opening of the hook body. The stop element is pushed into the projection prior to being completely cured so that it can elastically press upon and be retained in the opening of the hook body.
