A paper clip comprising:
- a length of a wire bent to form an oval loop with a first free end and a second free end comprising a partial outer oval loop and a partial inner oval loop disposed within said partial outer oval loop, said partial outer oval loop and said partial inner oval loop being generally coplanar with one another;
- said partial outer oval loop is concentric with said partial inner oval loop;
- said partial outer oval loop including an outer straight portion with said first free end forming a first U-shaped bottom portion connecting to a second straight portion connecting to a third straight portion by a second inverse U-shaped portion;
- a fourth straight portion connecting to said third straight portion by a third inverse “U-shaped” portion;
- and
- a fifth segment including a second free end extending outwardly and across said second straight portion at an angle;
- wherein said fifth segment can be biased inwardly whereby said second free end can engage said first straight portion securely holding a sheet of material therebetween;
- and
- a distal end segment extending from said outer straight portion at an angle between said first free end and said first U-shaped bottom portion for cooperatively interlocking and releasably engaging said fifth segment at an intersection of said fifth segment and said sixth segment.
