Secure attachment

A license plate attachment device comprising:

• a cap that covers a screw used to attach a license plate to an automobile, the cap including internal screw threads;
• a container onto which the cap can be attached, the container including external screw threads that match the internal screw threads of the cap;
• an anchor that when held tightly in place on the automobile by the screw, anchors the container and the license plate to the automobile so that the container can freely rotate while anchored to the automobile;
• a ring sized to fit over the container so that when the cap is attached to the container, the ring covers portions of the container not covered by the cap;
• wherein the ring contains a first pin hole and the container contains a second pin hole, the first pin hole being located on the ring and the second pin hole being located on the container at locations that allow the first pin hole and the second pin hole to be aligned to receive a pin that when placed through the first pin hole into the second pin hole allows anchoring of the ring to the container when the cap is being screwed onto the container.
