Abstract
An electric device, for example a shredder, comprises a cutter mounted on a base and driven by an electric motor, the cutter being concealed by a removable feed chute. A plug connector of a cord set is movably secured to the feed chute, and is moved towards and away from the feed chute to plug it with and unplug it from a plug connector of the motor. The plugging together of the plug connectors prevents removal of the feed chute; it being necessary to unplug the connectors to disconnect electrical supply to the motor by moving the cord set plug connector outwardly of the base before the feed chute can be removed to expose the cutter. Preferably, the cord set has incompatible plug connectors at each end to prevent a normal extension cord being plugged to said motor plug connector when said feed chute is removed.
