Lock for fast guns

I use locks for these reasons:

1. Ensure the turnbuckles do not release by accident
2. Ensure that no one releases my turnbuckle on purpose
3. Ensure that no one takes my turnbuckles for scrap value

These turnbuckles are very convenient with their quick release and fasten feature. I would not have the above worries with a screw type model but would lose that convenience.

Guess it depends on if you camp in a high crime area. I never lock mine.
