Abstract: A one piece locking device for securing kayaks and similarly shaped objects to stationary objects and automobile-mounted cartop carriers. The apparatus consists of a single plastic coated cable with a larger fixed loop at one end and two smaller fixed loops near and at the other end. The larger fixed loop is placed around one end of a kayak and the remaining cable passed under the crossbars of a cartop carrier and then around the opposite end of the kayak. By securing the two smaller fixed loops together with a lock, a loop is formed around this opposite end of the kayak. This newly formed loop and the larger fixed loop have approximately the same circumference, which is larger than the ends of the kayak but smaller than the cross-sectional circumference of the cockpit area of the kayak.
