Abstract: A locking device for securing and positioning an object when it is strung on a line by a through-hole of the object. The locking device includes an elongated shaft defining a partial cavity formed therein. The elongated shaft or a deepest portion of the partial cavity or both is tapered relative to a longitudinal axis of the shaft. The partial cavity extends along the longitudinal axis of the shaft, and the deepest portion of the partial cavity and the exterior surface of the elongated shaft forms a tapering angle. The locking device is inserted into through-hole of the object such that the rope or line fits into the partial cavity. Pressure may be applied to put the locking device into the through-hole such that there is no movement between the object and the line; thus securely positioning the object on the line. The locking device may be used to securely position a through-hole type boat fender on a line.
