You've found a swim bladder. Swim bladders are largely made from collagen, so when they're dried out on beaches they feel tough and rigid.

Swim bladders differ in shape between species. As an example, the swim bladders of oyster toadfish are similarly-shaped to the one you have found, but that general shape isn't uncommon, so it could have come from many other species.
