Atch,
I’ve simply pushed or struck the stainless piece with the heel of my hand to install them. I’ve always been careful to ensure the clip is indeed entering the hole in the sheetmetal, then give it a firm hit. I wouldn’t use a rubber mallet, because I’m sure it could dent the stainless. I could see using hog ring pliers to compress the clips to remove them, but they won’t work for installation. I’ve never seen any form of installation tool. Some light lubrication might help, or pulling the tails of the clips thru the hole with needle-nose pliers might help if you can get to the backside easily. Good luck
