Definitions

• a more specific object of this invention is to pro- vice a fastener that is easily mounted on a thin sheet pile as well as a substantially thick sheet pile.
• Another object of this invention is to provide a fastener that securely holds a thin sheet pile after being stretched by attaching to a substantially thick sheet pile.
• Another object of this invention is to provide a fastener that bears flat against the sides as well as the edge of a sheet pile and the like reducing excessive bulk when various piles are stacked.
• Another object of this inven ⁇ tion is to provide a fastener that secures firmly to the objects held and yet will be easily removed without damage to the sheet pile.
• Yet an additional object of this invention is to provide a fastener of the aforenoted character which is simple and economical to manufacture.
• Fig. 1 is a front elevational view of a wire fastener according to the invention.
• Fig. 2 is a side elevational view of the fasteners shown in Figs. 1 and 3.
• Fig. 3 is a front elevational view of an alternative embodiment of the present invention.
• Fig. 4 is a perspective view showing the fastener of Fig. 1 in use.
• Fig. 5 is a side elevation of the view shown in Fig. 4.
• FIG. 1 One embodiment according to the present invention is illustrated in Fig. 1 , generally comprising a single continuous length of wire 1 which is formed with torsion bar 2 from which bends 8 and 9 extend to form a looping element 3 and other element 4.
• Other element 4 is shaped to form a tab 5 and is shorter than looping element 3 to provide a mounting lip 7.
• Torsion bar 2 is preferably shorter than the perpen ⁇ dicular distance from torsion bar 2 to curvature 6' of looping element 3. Moreover, fastener 1 is formed such that all its elements lie on the same plane, as shown in Fig. 2.
• Tab 5 preferably formed by bending other element 4 into a loop, is shown in Fig. 1.
• fastener 1 is disposed upon a paper pile or the like as illustrated in Figs. 4 and 5. Entry of the papers to be held into fastener 1 is achieved by placing lip 7 on edge 11 of one side of paper pile 10, then spreading elements 3 and 4 by depressing tab 5. When fastener 1 is in place, both elements 3 and 4 and torsion bar 2 lie flat against the sides and edge 12 of paper pile 10, as shown in Figs. 4 and 5.
• FIG. 3 An alternative form of the present invention is that illustrated in Fig. 3. As before, both elements 3 and 4 are formed in the same manner as previously described except tab 5' is formed to cover entire area 15 confined within the perimeter of other element 4. Tab 5' is
