Abstract
A locking device 100 is inserted within the disk drive (11) of a personal computer ("PC") 12 to prevent unauthorized use thereof. The locking device (100) includes a pair of pivoted plates (101, 102) retained in their expanded locking position within the disk drive (11) by means of an externally-accessible padlock (107) or its equivalent. Each of the plates (101, 102) carries a spring finger (109) which "bites" into the adjacent respective side rail (26) in the event that an attempt is made to remove the locking device (100). The locking device (100) is inserted into the disk drive (11) in a one-handed operation and in its locked position. In another embodiment, a key-operated lock is carried on one of the pivoted plates.
