A fastening device for a bundling band comprises a grommet and a punch. The grommet is provided with a tubular insertion part incorporating therein a hollow inner passage for admitting opposite ends of a bundling band, a flange part formed at one end of the insertion part as extended from the outer wall of the insertion part, and a supporting part projected from the outer wall as opposed to the rear side of the flange part. The insertion part is provided on one of the opposite outer wall surfaces thereof with a pin extending outwardly therefrom to a length greater than the distance between the opposite outer wall surfaces and connected at the base portion thereof with the outer wall through a thin-walled peripheral part and on the other opposite outer wall surface thereof with a perforation formed therein in a diameter greater than the diameter of the pin. The punch is provided at the leading end thereof with a projection of a diameter smaller than the diameter of the pin and adapted to drive the pin into the perforation of the grommet.
