I lost an identical clip for my lawn mower last week. I looked all around the area I was working but couldn't find it. I gave up and headed for the garage to find some sort of make-do solution and happened to look down and saw the clip 30 feet from where I was working.
It took off like a rocket, I guess, and landed just about under one of the cars in the garage.
