It's a clip made to protect the cable chain and the PTFE feed tube from rubbing concerningly and noisefully on the side panel screw.
It's designed to simply be clicked on and need no adhesive or other parts to fit in place.
It will probably need a small lever or stick to be removed. But you won't need to remove it to screw off the panel.
Actually you'll probably never have to detach it, so… Make sure the logo it's upside up when you install it. Ask me how I've thought. ;)
