1970 Fuse Block repair

Thanks for everyone's response.  I thought about soldering but you need a propane torch cause copper needs to get really hot.  I may have to drill out the rivets and remove the clips.

I have a 70 mustang coupe. I was changing fuses and the Black-Yellow stripe wire connected to copper broke. I'm having a difficult time identifying its use. It was attached to the 14A/20A copper connector.  Also, is there a way to repair this connection.
