Abstract: This invention discloses fasteners characterized by the use of barbs to secure a primary object in place. More particularly, the barbs which are used are critically shaped barbs resulting in considerable increase of the holding force without sacrificing the flexibility of the barbs, the force needed to insert part of the primary object into the fastener, and without sacrificing the broad acceptability of various thicknesses of the primary object to be fastened. The distance between the front point of a barb and the respective opposite side structure may preferably be smaller than the thickness of said material, such as sheet metal for example, that the fastener is made from. The fasteners of this invention may also be provided with spring members of intricate and critical structure, which despite easy insertion of the fastener into a slot of a secondary object, the removal force is greatly increased.
