Antique below elbow prosthetics from the 19th and early 20th century. JM Barrie didn't just randomly go with a hook. We only really see the end of the prosthetic in the show, but Killian would absolutely have some kind of similar cuff or straps around his upper arm and probably some kind of harness across one or both shoulders in order to keep his hook from getting yanked off of his arm when he uses it for things like stabbning people or climbing.
