Ok, I tried all the other recommendations, not all would hold securely. Some popped out over night.
Some seem to hold, but I really don't trust them.
I think I found the definitive solution...
I took a 1/16" vacuum port cap and pushed it over the clip, went most of the way down, but left a little on top.
They must be pushed in forcefully, but these are in FOR GOOD. Pretty sure I would have to break them to get them out.
These are not going anywhere EVER....
