"Metal clamp over breaker?? Plumbers worked on water heater and left. Checked breaker and found this"
A: "It’s definitely an LoTo device, possibly an Eaton branded one from Home Depot. There is no padlock on it, so you can still move the breaker switch below it freely, so just leave it alone and ignore it. More trouble than it’s worth! It’s just over a flat, block-off plate anyway."
It's a toy missile. I had a million of these in the 80s when I was all about Transformers. The color also makes me think it's part of a toy. You would insert it into a launcher, a spring would get stretched out as you as you loaded the missile, and once it's fully inserted that hook on the end would catch onto something securing it in place. You would press a button somewhere on the toy releasing the catch, and the tension in the spring would send it flying.
