I recently upgraded to a Neptune 4 Plus, and noticed the tensioners reportedly have a tendency to loosen. I tried a few of the existing tensioner locks, but they seemed to have nothing to prevent them from sliding off due to vibration.
After trying a few different approaches I cam up with a simple two-piece design that has a clip that lifts up and down to go behind the adjustment knob and prevent sliding off. It also unlocks and slides off easily using a single hand.

Tested on a Neptune 4 Plus, but should also work for the 4 Max and the corresponding 3 versions. If anyone tries this out on the other models, please leave a note in a comment.
