you can make repairs useing short lengths of copper pipe and hose clamps. I tried wraping with wire. Didn't stay tight enough. Use hose clamps, the narrow ones.

Hose clamps are pricey. Might try using nylon cable ties. I can see getting more even tension than with wire, and they are a lot cheaper.

Also: Put a film of shoe goo on the pipe insert before inserting.

I know this is a little late, but they make drip tape couplings. You just cut out the bad spot and they hook right back up. If you are not sure what I am talking about, they have them at tcdrip.com

Electrical tape wrapped around the break while the drip tape is pressurized works here

Amazingly, electrical tape sticks to itself even while wet

fast and cheap
