Claim:
A trailer security system for use with a trailer including a trailer coupler channel including a web and including first and second flanges extending in a first direction from the web, each flange including a plurality of holes aligned with holes in the other flange for joining a trailer coupler to the trailer, the trailer security system comprising: an apparatus including a longitudinal axis and including four walls with each wall joined to at least two other walls, and the four walls defining a substantially enclosed space sized for receiving at least a portion of the first and second flanges; at least one of the four walls including parallel first and second slots defined by three wall sections: a first wall section, a second wall section including a tab having an aperture defined therein, the tab having a width that is less than a width of a remaining portion of the second wall section, and a third wall section, the first and third wall sections extending lower than the second wall section, each slot including a first closed end and a second open end, where a first side of the first slot extends substantially along the length of the first wall section to the closed end, a second side of the first slot extends from the closed end substantially along the length of the second wall section to the tab, a first side of the second slot extends substantially along the length of the third wall section to the closed end, a second side of the second slot extends from the closed end substantially along the length of the second wall section to the tab, and each slot including a longitudinal axis that substantially parallels the longitudinal axis of the apparatus and each slot providing access to the substantially enclosed space and sized to receive one of the first and second flanges therethrough; wherein receipt of the at least a portion of the first and second flanges into the substantially enclosed space substantially restricts access to at least one of the plurality of holes in each flange thereby substantially preventing attachment of a trailer coupler to the trailer coupler channel.
