This will end up being part of another thing I'm designing, but since I split that into components, and this seems like it might be useful on its own, I thought I'd just upload it and see if it captures anyone else's imagination.

It really isn't anything groundbreaking, but I couldn't find anything like it elsewhere, so I made it. You just "borrow" the spring from a standard clothes-pin and snap it into the two pieces to make a special kind of clothes pin (or is it one word... clothespin?...) that is bent in a right angle (and quite a bit shorter in the "jaws," but that's where it suits the other purpose I have for it).
