It doesn't look like it's constructed to be a tool. The closest thing I've found is a brass welding clamp. They have much stronger springs, a way to connect the proper wires to it, and ridged surfaces in the clamp. That has none of those. If that were designed to do anything as a tool, the only possible use I can think of is tk maybe attach something flat to a pipe, like making a screen from a pipe frame. Even then, that spring is too weak to hold much, and the brass is way too much overbuild to be cost effective as anything other than decoration. The only other thing I found that looks somewhat similar is a wine bottle display holder.
