Abstract: The closed loop cable system was designed for preventing the theft of coats, but could be used for many other applications. When used for theft prevention, a length of cable is passed through one or both sleeves of the coat to form a loop, and the cable ends, which are provided with mating ferrules are then mated together and then crimped. The cable loop through bath sleeves prevents anyone from trying the coat on, and through one sleeve enables customers to try the coat on, but alerts clerks that it has not been paid for, and thus prevents anyone from putting a coat on and walking out without paying for it. A specialized tool is used to crimp ferrules on the ends of the cable together, and the same tool can be used to cut the cable.
