It's to do with limiting electromagnetic interference (EMI). I'm not sure of the exact function, but they're not fuses. They may contain a capacitor which is connected to ground on one side.

If you're sure the function of that part is affected (and not just cosmetic damage) you could probably remove it and solder a wire link in its place. But first I'd check with a multimeter/continuity checker, as replacing it may not be necessary.

Edit to add: it's possible that something like the products shown here contain similar components embedded into them.
