ABSTRACT:
A snap-fit fastener having deflectable, diverging wings extending from a distal end of a pedestal is provided with lead-in extensions from the connection of each wing to the pedestal. The extensions define a slot therebetween and are curved relative to the wings. By inserting an implement such as a screwdriver in the slot and twisting the implement, the lead-in extensions are spread relative to each other and the wings are moved toward the pedestal to allow the fastener to be disconnected from an object.
