Abstract: An antitheft device for a port replicator includes a case with a plurality of ports and at least two locking holes. A locking mechanism is locked into one of the locking holes. An actuating lever is provided at one side of the case and receives an actuating force to separate a portable computer from the port replicator. A link mechanism is driven by the actuating lever. A locking plate prevents the actuating lever from being operated when the locking mechanism is locked into one of the locking holes. Therefore, the port replicator and portable computer can be prevented from being stolen by having the portable computer and port replicator locked with each.
