Tricer LP pan head, how to create a lock??

[plentycoupe]

So I bought this tripod and LP head to give it a try and all looks great.....except I can't get over the fact that it does not have a "safety" lock on it like the Sirui.
Over the years I have forgot to tighten my bino post or spotter onto my Sirui head and was saved from dropping the optic do to its push button safety.

I really like the Tricer and will head out to WY in a couple weeks to use it for the first time.

Does anyone share this thought process and have an idea create some kind of lock or catch??

Thanks.
