what type of connection or fitting is this?

Google 'wire spring clip' and look at images. Could be a hose clamp or tube clamp.

Here's one of many...

Thank you. I couldn't remember what it was called. I wonder if it's possible to modify some small springs I have into one of these? I would

need to first compress the springs because they won't current fit the terminal post. I bet I don't have the heat to do it though, but may try

and find some of these fittings locally.
