The invention further discloses a retractable pull-handle system that contains such a locking mechanism for use on wheeled luggage cases. Inclined surfaces are provided on the vertical and the horizontal sliding blocks such that when they are intimately mated together in a lock housing, vertical movement of a pull cable can be converted to horizontal movement of a locking pin.
