Zapasznik (m)
hook, &c. at the lower end of the bellows, to be shoved behind the waist strap
Most probably from "za" [behind] + "pas" [belt]; Protruding element on the bottom cheek of the bellows, used to hold the latter in position by putting it behind the trouser belt of a gajdosz.
Made of metal or, in older instruments, wood.
