Removing clips on bumper

[DoubleV]

OK this may seem like a silly question but I just wanna be certain. I'm attempting to remove the black plastic strip off my front bumper ( 78 cutlass ). Everything's removed accept for these shown in pic.

So are these clips meant to be replaced after you pry them open or do I gotta be gentle and pry just enough to allow the nub of the strip to slide out?

can;t see them in your picture are they the same black plastic the strips are made of ? if so they are probably part of the strip not made to come out but you can hammer a screwdriver with the tip on the black plastic on one side then the other better pic will help are you putting on new strips ?
