Broken CMOS Battery Clip

Hello,

I have a motherboard that requires a CR2032 battery both for the internal clock and to preserve CMOS settings when unplugged. The slot resembles this model:

I have accidentally broken the clip that holds the battery down while trying to change it. I’m wondering what are my options. I’m thinking I can safely keep the battery in place with a small quantity of hot glue (it’s a well vented ATX case) but does that clip not serve as the cathode? What is the simplest way for me to fix this? I should add that I’m not very at ease with soldering, but I’m ready to give it a try if necessary and, I know I’m betraying my carelessness here, but I think I’ve lost the broken clip part.
