Oldham Jig Rattle

I bought a bag of these rattles and cannot figure out how to connect them to the jig. I know it’s probably easy, but I’m stumped. Anyone know how they are designed to connect to this jig?

the rattle hangs freely on the shank of the hook. Rubber stopper keeds it from coming off

Loop it through your hook keeper, put the craw on. Craw holds it onto the hook. It’s swings on hook and rattles.

Thank you. I figured but it doesn't seem very secure with the rubber they sent with the rattle. I appreciate the feedback.
