Abstract: Provided is a trailer hitch coupler locking device for preventing the unauthorized use or theft of the trailer when stored or otherwise unattended. The locking device includes a lock mechanism configured to move a ratchet member from a first position where the ratchet member is engaged with an elongate member to a second position away from the elongate member where the members are disengaged. The elongate member is movable from a first position where an end of the elongate member is proximate a hitch ball to hold a trailer socket between the end of the elongate member and the hitch ball, and a second position where the end of the elongate member is spaced from the hitch ball to allow the trailer socket to be moved away from the locking device.

Abstract: A coupler lock for attaching to a trailer hitch coupler. The hitch coupler has a socket. The coupler lock includes a locking bar and a plug member for receipt within the socket of the hitch coupler and supported by the locking bar. The coupler lock includes a base structure removably attached to the locking bar. The base structure includes a locking structure actuatable to lockingly retain the base structure attached to the locking bar so as to retain the plug member within the socket of the hitch coupler. The locking structure is positioned above the plug member with the base structure attached to the locking bar and the plug member retained within the socket of the hitch coupler.
