If the little barbs are not going back in, straighten them out with pliers and heat them up and they will melt back into the plastic. Allow time to cool or it will pull right back out. If they are just pulling back out and not staying, Ive mixed 2 part high strength epoxy and used one small drop at each barb to secure it back. After its fixed, here's the trick, smear a little grease on the spring loaded fingers so it will pop in and out smoothly. IF there are some stubborn ones, don't pull from the plastic, but insert a thin blade or scraper underneath and gently pry up.
