A security apparatus for preventing unauthorized disengagement of a charging connector from a charge port of an electric vehicle, for example during the battery charging process. A lock member is disposed on the electric vehicle and is movable between a locked position wherein it inhibits disengagement of the charging connector from the charge port and an unlocked position wherein it allows disengagement of the connector from the port. A locking actuator located adjacent to the charge port is manually actuatable to move the lock member to the locked position. An unlock actuator disposed inside a vehicle cabin is manually actuatable to move the lock member to the unlocked position. This ensures that only a person with access to the interior of the vehicle can unlock and disengage the charging connector from the vehicle.
