Fixing leak in A/C line (aluminum hard line)

The other day I was working on a friend's 2000 Saturn LS200 sedan. I fixed his evap problem, and he mentioned the A/C wasn't working. So, we ran to the store, bought a can of R-134a and put it in. Still nothing. We drove it back to my house, popped the hood and I listened. I tracked down the slight hiss and found a leak in one of the low pressure side aluminum hard lines.

My question is, how can I go about repairing this? I know I can replace the whole line for about $80. But, is there a simpler solution? Can I patch it with some goop and a hose clamp or something like that? How much pressure does it need to hold up to? How cold/warm does the low pressure line get?
