Finally I tried 'Liquid Nails' brand of super-super glue (Home Depot). I roughed up the ends, put plenty of glue on both side, stuck them in my vice and left them set for 24 hours. So far, so good.

I ended up buying 4 9 volt connectors from Radio Shack and attaching two to each end, one to the ‘-‘ and one to the ‘+’. I have a crude wiring diagram if you would like it.
It has been working great, it survived this this morning:
