It's different for every different side pivot snap shackle (the "normal"
type). There's a minimum bend radius required for reliable release,
depending on the exact shape & pivot point. I recommend using a tip pivot
shackle instead, or at least opening the side pivot shackle & trying to MAKE
the object get stuck on the open end. If you can make it stick, there's a
chance it will stick when you don't want it to.

Side pivot: see above.
Tip pivot: see my recent post - anything I've tried will work (check with
your own parts before use).
