A device for securing fenders and other objects to the safety rail of a boat includes a tubular portion terminating at one end in a converging configuration that function as a jam cleat when a line is worked through the tubular portion from the opposite end, with the emerging end then pulled laterally into engagement with the convergence. The device preferably continues beyond the converging configuration to form a hook that can be snapped over and resiliently grasp the boat's hand rail. The device is preferably made in a sequence of operations formed on a piece of thermoplastic tubing, involving splitting the tubing along a fraction of its length, and then opening the split portion to form the convergence. This portion is flattened to also form the hook configuration.
