Abstract: A hook for fixing a decorative band to a hat has needles in the form of a fishing needle. For safety, a hole 11 is formed at the center of an elastic iron plate 10 which is bent toward one side. A sharp needle 11 is formed at one inner side of the hole 11, and needles 13 and 14, each in the form of an arrowhead are formed symmetrically outside of the elastic iron plate. A cleave 11a may alternatively be formed at the center of a flat elastic iron plate 10a with a sharp needle 12a formed at the opposite side of the open side of the cleave 11a. A needle 14a, in the form of an arrowhead, is formed outside of the open side of the cleave 11a, with knobs 15 which are inclined downwardly formed symmetrically outside of the open side of the cleave 11a.
