I would not use a clip on a worm hook. Nobody would stop you, but the worm hook would have a ton of action that you may not like for the worm.
One of my boys tried it, though, and he did happen to catch a yellow perch. So yeah, it'll work, but it isn't best.
On all my worm hooks I tie a snell knot. It is easy and super strong as it pulls the hook by the shank, not the eye. Here's a simple video from YouTube from a catfisherman that shows how easy it is:
I use this on my wacky, and drop shot hooks down to size 4, too. TX rigged J hooks, EWG, etc, all snelled.
