I'm not aware of any locks but I can think of a couple solutions as we had a concern a few years back. The easiest is Valterra sells a clear view waste cap. While this doesn't necessarily solve the problem, it does allow you to see what your dealing with beforehand so you can limit exposure. If nothing else, these caps are practical because other mistakes happen and valves fail.
What we did is install a twist-on valve like this. It allows a double layer of protection with the valve so you can close it at the cap, hook up your hoses, then open both valves up. Better yet, get both solutions!
Good luck,
