ABSTRACT:
An electrical connector (10) for a detachable power cord (18) that can be selectively locked in place when engaged in a standard appliance power socket (80) of an electrically powered applicance or device that utilizes a detachable power cord, such as a personal computer or a desk-top laser printer, for instance. A securing means (64, 88, 106) is provided to prevent removal of the connector from the appliance power socket, which in turn prevents circumvention of any access-control means that may be operatively associated with the power cord. A controlled-access operating means (30) is provided whereby an authorized user can lock the connector into or unlock the connector from the appliance power socket.
