If you mean the retractable part is loose, I had the same issue last week with the rope getting caught in cleat all the time.
If your cleat design is similar to an early 2000 Malibu, it's a simple fix. Unscrew the phillips rounded head screws that are holding the cleat from the back and bend the washer tabs outward to create more friction. Reinstall and enjoy.
If the whole cleat is loose, just tighten the large hex nuts.
