Abstract
A locking device (10) is inserted within the disk drive (11) of a personal computer (12) to prevent unauthorized use thereof. The locking device (10) includes a part of pivoted plates (15, 16) retained in their expanded locking position by a key-operated lock (20) carried by the plates (15, 16). Each of the plates (15, 16) carries an arresting mechanism (35) which expands within the disk drive (11), in the event that an attempt is made to remove the locking device (10), and "bites" into the adjacent guide rail (53), thereby stopping any further movement of the locking device (10) out of the disk drive (11).
