[CR]Help removing circlips from my Mavic front derailleur

Hello list,

I'm in the process of disassembling my fully "démontable" Mavic front

derailleur, but am caught: I just don't know how to remove the small circlips. I tried pliers and the sharp points of compass sets, but neither worked.

Here's a link to a photo of the derailleur, showing the circlips:
