Abstract
Abstract A license plate fastening and locking system by which a motor vehicle license plate is locked in place directly on a support, e.g., the bumper, of a motor vehicle. At least one key operated locking member fastens the license plate to the bumper. The locking member includes an outer cylinder passing through openings in the license plate and bumper, with the outer cylinder having an annular end collar clamping the license plate against the outer face of the bumper. A key plug extends through a central bore of the outer cylinder and is key operated between unlocked and locked positions. When moved to the locked position, the plug actuates a locking retaining member positioned adjacent the inner end of the cylinder into locking engagement with the inner face of the bumper to prevent unauthorized removal of the license plate and/or locking member from the bumper.
