Abstract
Abstract A lockable securing device including a bifurcated body having a pair of outwardly extended, spaced, parallel arms. A slotted opening is formed between the arms. Transverse apertures are provided in the arms near their outer ends and are sized to receive a removable, axial locking device. The locking device has an extension member at one end which is arranged to extend across the slotted opening to block the opening and retain an object within the slot when the axial lock is inserted and retained within said body arms. In one embodiment the slotted lock is used to secure the frame of a bicycle to an anchored object to prevent unauthorized removal; another is a door handle.
