I know, I have them too, you probably wont be able to find the same kind, but you can find one that's the same size as the hole so that you can keep the strap in place. As for a replacement strap, you can either find an older pair of pole and just take those straps off and use those or get some sort of similar fabric and make your own strap. If you really want to you can contact Line and see if you can get a replacement.
