Abstract

Abstract A fixing device for joining two sheet parts as separated by a prescribed space from each other is disclosed which comprises a hinge part adapted to be bent perpendicularly, a base plate part connected to one end side of the hinge part and provided with a projecting fitting shank, and an engaging part connected to the other end side of the hinge part and provided with a pair of legs possessing engaging claws at the leading ends thereof and a retainer claw possessing an upwardly urged free end. By this fixing device, a lower sheet part is fixed in place by boring a hole in advance along one edge of the lower sheet part, inserting the fitting shank, and bending the hinge part perpendicularly thereby bringing the engaging claws into fast engagement with the lateral walls of the fitting shank and an upper sheet part is fixed in place by pressing the upper sheet part downwardly from above the engaging part held upright and allowing the upper sheet part to be nipped between the engaging claws and the top of the fitting shank.
