How to get parking brake cables off rear axle??

well i went at it a little today and didn't have much luck, it didn't get very warm out today so i wasn't able to stay out in very long. I got a hose clamp but it's a little too small i think and i can't seem to get it around the fingers. do you guys think if i found a really small gear clamp if that may work? I'll give it another try tommorow maybe, i'm hopeing it'll warm up around here just a little so i can be out there a little longer. Any other suggestions?
