Outer Limits 4x4 Board

I want to lose a couple of leaves from the packs but im not sure how to deal with the spring clamps/retainers or what ever their called.

I know my mates lux has them and he spread them open to get more flex and they dont fall out , so how do i get them out or off , and replace them ?

Lever them open with a screw driver and leave them open, don't have to go all the way just enough to get the springs out.

so the bottom spring that had the clamp on it at the bottom will just drop off then?
