Abstract: A known locking device for preventing the theft of golf clubs held in a stand includes a cable defining a noose that fits through the hem of a hood covering the heads of the golf clubs. The cable passes through a handle of the stand and around a fixed object. The ends of the cable are fitted with eyes and are connected together with a padlock. A problem with this arrangement is that the noose can be loosened by a thief, allowing removal of the hood and then of the clubs. The problem is solved by the use of a locking sleeve (6) that can be adjusted between a release condition in which it can slide along the cable (4) to tighten or loosen the noose (3A) and a secured condition in which it is restricted from sliding. Means is included for locking the sleeve in its secured condition so that the clubs cannot be removed.
