i have done it
i did damage it, the large red clip came off, the holder inside came off but i hope i have helped with the picture.
The first pic shows the inside if the clip, the bit you cant see.
I have highlighted the holder that the actual clip hooks onto. This did break because i didnt undo it correctly but if it was undone correctly, im sure it would of been ok.
the second pic shows the outside or the clip as it is normally. this is very important to get this bit right. i have highlighted the clip as a whole but used a red line to show where you DO NOT lift up. Where the red line is there is a gap that looks like you put a flat head screw driver in and push the clip Down, you do not! You put the flathead screw drive under both 'tongues' and lift up the lot. there isnt a lot of lift available and the hook your trying to lift up from the holder i talked about earlier is a substantial size. this means you dont quiet have enough lift of the tongue to bring the hook up and off the holder.
its difficult, and problems i will try to help.
