The present invention provides a trailer coupler lock assembly for securing a coupler whether attached to or detached from a hitch ball of a trailer or vehicle, the coupler attachable to the hitch ball supported by one of the trailer or vehicle, the locking assembly having a first bracket member and a second bracket member, each of the first and second bracket members having a locking tab with a locking bore. A hinge connects the first and second bracket members, the first and second bracket members having an open position and a closed position, the first and second bracket members configured to form a body receiving cavity disposable about the coupler and lock thereto when the first and second bracket members are in the closed position, the locking bores being disposed in axial alignment to receive the shackle of a padlock there through.

1. A trailer hitch coupler lock assembly for selectively locking a sliding collar in a coupler of a trailer hitch, comprising:a first bracket comprising a locking tab defining a first locking bore at a first end of the first bracket;a second bracket comprising a locking tab defining a second locking bore at a first end of the second bracket;a hinge interconnecting opposing second ends of the brackets permitting movement between an open position and a closed position, the brackets defining a cavity in the closed position that is closely matingly engageable with a cross sectional perimeter of a member upon which the collar is slidable, thereby preventing movement of the collar to the open position.2. The trailer hitch coupler lock assembly of claim 1 wherein the coupler has a handle for moving the collar between the open and closed positions, and wherein the cavity defines a notch that is receivingly engageable with the handle in the closed position of the brackets.3. The trailer hitch coupler lock assembly of claim 1 wherein the bores are aligned in the closed position of the brackets, the bores defined by recessed opposing surfaces of the tabs for adaptively concealing a locking member passing through the bores and fixing the brackets in the closed position of the brackets.4. A trailer hitch coupler lock assembly for securing a sliding collar in a coupler of a trailer hitch wherein a hitch ball is secured to one of either a vehicle or trailer and the coupler is secured to the other of the vehicle or trailer, the coupler having a body and a cap pivotally supported by the body, the body and cap forming a cavity for receiving the hitch ball when the body and cap are closed thereon and releasing the hitch ball in an open position, and a collar mounted on the body having a releasing position to allow opening of the body and cap and a latching position wherein the collar moves the body and cap to the closed position, the trailer hitch coupler lock assembly comprising:a first bracket comprising a locking tab defining a first locking bore at a first end of the first bracket;a second bracket comprising a locking tab defining a second locking bore at a first end of the second bracket; anda hinge interconnecting opposing second ends of the brackets permitting movement between an open and a closed position, the brackets annularly defining a cavity in the closed position configured for an interference fit with a cross section of the collar preventing a sliding receiving engagement of the collar in the cavity.5. The trailer hitch couple lock assembly of claim 4 wherein the coupler has a handle for moving the collar between the open and closed positions, and wherein the cavity defines a notch that is receivingly engageable with the handle in the closed position of the brackets.6. The trailer hitch coupler lock assembly of claim 4 wherein the bores are aligned in the closed position of the brackets, the bores defined by recessed opposing surfaces of the tabs for adaptively concealing a locking member passing through the bores and fixing the brackets in the closed position of the brackets.7. In a coupler for a hitch ball having a cap with a fixed portion and a hinged portion moveable between a closed position to couplingly engage the hitch ball and an open position to couplingly disengage the hitch ball, the coupler further having a tongue attached to the cap and a collar circumscribing and longitudinally slidable on the tongue and the cap between a locked position engaging the hinged portion for retaining the closed position and an unlocked position disengaging the hinged portion for permitting the open position, the collar extent of travel in the locked position defined by a wedging engagement of the collar against the hinged portion, the collar extent of travel in the unlocked position defined by a shoulder abutment portion of the tongue, an improved lock comprising a body with a cavity defined by an internal surface that is closely matingly engageable with a circumferential portion of the tongue adjacent the shoulder to abuttingly engage against the collar on one side of the lock and abuttingly engage against the shoulder on the opposing side of the lock, preventing collar movement to the unlocked position.
