What tool do I need to disconnect the automatic transmission lines on my 2005 TJ?

They are GM quick connect fittings, lots of places sell the tools. Don't know a specific part number or anything, mine doesn't use them.
 
I used a Sharpie marker cap to disconnect mine. Cut the closed tip off and a slit down the side to slip it on the line. Worked like a charm.
 
I just pulled these from my buddys jeep, I just used a pick…. Not sure why you would need a special tool?

I've done the same with a pick or small screwdriver, but I think the tool makes it easier when you go to install the clip.
