Abstract
An anti-theft device is provided which, when used on a trailer coupler, locks on to the trailer coupler and covers the receptacle of the coupler, thereby preventing the insertion of a hitch ball or other towing means into the receptacle. Locking engagement is achieved by a retaining member being moved and held in a position inside the receptacle of the coupler by the operation of a lock housed in the body of the anti-theft device. In another embodiment of the invention locking engagement is achieved by the retaining member being moved to a position inside the coupler receptacle through operation of a lever independent of the retaining member and being held in such position through operation of a lock housed in the body of the anti-theft device. No tools or auxiliary parts are required to attach or remove the device.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
