I use a Guardian coupler lock.

Here are two pics for you.

Hi, I use the Guardian G-37 on my 2 5/16" rolled lip coupler. Note: in the second picture, I cut out a horse shoe shaped, piece of tire sidewall, and glued it to the inside on top. This made it fit tighter and won't harm the paint on the coupler. I did this mainly because it fit a little bit too loose for my liken.
