Lol, those are quick release fasteners. The first time I saw them was in a video demonstrating a car that was too low to go over a speed bump and snapped the bumper tabs / clips. The solution was the quick release fasteners so the bumper can be taken off of the car entirely, or quickly fastened back into place if a road hazard pops it off.
