Patent abstract
A substantially spherical ball made of tough plastic fits in the coupler cavity of a trailer and is secured to the trailer safety chain by a zip tie, cord or cable. It is locked in place by a padlock through the lever on the coupler ball hitch. Thus it prevents a potential thief from quickly temporarily hitching the trailer to his/her hitch ball.
