Abstract
An anti-theft mechanism for a trailer coupler designed such that it can be locked or secured to the coupler is such a manner that the coupler cannot be utilized. The mechanism includes a body, which is securable to the trailer coupler. The body includes a retention portion that is sized to mate with the lip portion of the trailer coupler. The mechanism also includes a lock cylinder, an extension member attached to the lock cylinder, and a locking pin moveable between retracted and extended positions. When the lock cylinder is rotated from the unlocked position to the locked position, the extension member moves the locking pin from the retracted position to the extended position.
