needing to replace clutch pipe A, a hydraulic line that connects to the clutch master cylinder?

I am needing to replace clutch pipe A, a hydraulic line that connects to the clutch master cylinder. I replaced the clutch master cylinder and damaged the original pipe in the process. :-(

The clutch pipe is held to the car body by what a diagram describes as "tube clips." My question is - how can I remove these clips in a way that I don't damage them? I want to use them on the new pipe.

Thanks for your help!
