Ikea PAX Door Disassembly / Hinge Problem

Hello,
I want to dismantle a Pax again. But how do I open the hinges again? They are clipped in and cannot be "unclipped". The cabinet is from 09/2009.
Regards and thanks in advance, Pegman

Pull the hook forward and remove the arm. If there is tension on it, it will be correspondingly more difficult. But actually quite simple.
