Repace Clutch Hydraulic Line

I have a 2007 Chevy HHR that has a bad clutch hydraulic line. My question is how do I disconnect the line from the slave cylinder? i don't want to mess up the slave cylinder and need to remove the trans.

The problem has been resolved I took the car to a local transmission shop and had the new line installed. i believe they left the old bleeder valve in the slave cylinder and used a tool to separate the line and bleeder valve.
