Abstract: A webbing fastener of a luggage article comprises a webbing and a hard rubber part. A face of the hard rubber part includes a webbing insertion slot, and the left end of the webbing is formed in the webbing insertion slot. The bottom side face of the hard rubber part includes several positioning cylinders, the right side of the cylinder includes a slot. A slider with a threaded hole is mounted in the cylinder The slider includes a bump mounted in the slot. The outer end of the bump includes a compressing edge, the compressing edge is mounted in the slot, the compressing edge compresses the left edge of the webbing, and the compressing edge is positioned at the right side of the several positioning cylinders. The webbing fastener is beneficial because punching holes on a webbing is unnecessary, easy assembly, and loosening after assembly is prevented.
