The clip is small and has a set of teeth. So you place it where you want it open it and snap it shut. The metal has a slight bend to it that allows it to snap. I don't know if that helps
open what part though? I see all these pieces on it but I don't want to break anything! lol do the teeth stay closed? that little round thing at the end is that what's supposed to "snap" when I got my black one I ordered the spring and pin were a little bent so idk if that's what's not making it bend like you say it's supposed to... I'm not sure though, I've never had one of these lol. still trying to figure it out lol. sorry for the questions lol I just really am confused on this lol. but I'd really like to try this style out... thanks for any help. greatly appreciated. may god bless
