The clips for this application with which I'm familiar are nothing more than so-called "speed nuts," available at your local hardware store. They come in different shapes (e.g., rectangular vs. round), diameters and thread pitch.
Easy to install -- just push them on using a pair of needle-nose pliers or a small socket. To remove them, use the pliers and bend them in the opposite direction -- they come right off.
Adhesives are fine, until they don't work any more. There's a reason the factory used a mechanical fastener.
