There is disclosed herein a relatively simple locking device for sporting items such as skateboards, snowboards, snow skis, and the like. In one form of the locking device, the same includes a member which can be affixed to a wheel truck of a skateboard, binding of a snowboard, or binding of a snow ski, and includes a releasable cable which can be wrapped around a fixed or stationary object so as to secure the sporting item. In one embodiment, the cable can be extended and retracted from the body of the locking device so as to provide a suitable length of the cable for the securing function. In another embodiment, the cable is normally retained in a flanged section of the locking device, but can be released therefrom for attachment to the fixed or stationary object. Another embodiment includes a removable cable and lock, and a further embodiment provides a relatively simple locking bracket, particularly for use between the wheel truck and board of a skateboard and which can be used with a separate cable and lock.
