That way the curve helps stiffen the connection. Also additionally secure with a twist-tie, twisting extra to cinch it all up.
It's the mirror end; the wire inserted into the lucite mirror, by which it attaches to the rest of the metal structure, just won't stay tight. Typically it gets loose because the mirror is working its way off the wire, so you tighten it by pushing the wire back in. But I've done that so many times that that trick isn't working any more.
But you make a good point; all I need to do is do something to the wire to increase friction. I'll try putting a dent in it with a wire cutter, or maybe bend it a tiny bit. That should get me through....
Inspired by this thread I looked on eBay, and saw this:

I couldn't resist. I ordered two. I'll report back in a month or two (shipping from China has been getting faster, but it can still take for ever).
