  "claims": [
    "1. (canceled) 2. (canceled) 3. (canceled) 4. (canceled) 5. A clamp comprising: a clamping portion having a clamping face, a back surface, a top portion, a bottom surface, an angled surface, an elongate opening having a longitudinal axis that is perpendicular to the angled surface; a lower gripping element disposed near the intersection of the bottom surface and the clamping face: wherein the angled surface is at an angle of between 20 degrees and 30 degrees with the back surface; wherein the lower gripping element is perpendicular with the clamping face, extends outwardly from the clamping face, is transversely continuous across the clamping face to extend from a left surface and to a right surface of the clamping portion, and is disposed near the intersection of the bottom surface and the clamping face of the clamping portion; wherein at least a portion of the lower gripping element has a flat face portion parallel with the clamping face; and, an upper gripping element disposed near the intersection of the top portion and the clamping face. 6. The clamp of claim 5 further comprising an upper gripping element that is perpendicular with the clamping face, wherein the upper gripping element extends outwardly from the clamping face and is transversely continuous across the clamping face to extend from a left surface and to a right surface of the clamping portion. 7. The clamp of claim 6 and wherein the upper gripping element includes a cross section that includes a pointed portion. 8. The clamp of claim 7 wherein the upper gripping element has a general cross section of an ogee having one of either a curved upper section or an angled upper section, and wherein the ogee protrudes from the clamping face and wherein the upper gripping element protrudes perpendicularly from the clamping face. 9. A clamp comprising: a clamping portion having a clamping face, a back surface, a top portion, a bottom surface, an angled surface at an angle of between 20 degrees and 30 degrees with the back surface, wherein the angled surface includes an elongate opening having a longitudinal axis that is perpendicular to the angled surface; and, a lower gripping element disposed near the intersection of the bottom surface and the clamping face wherein the lower gripping element is parallel with the clamping face, extends outwardly from the clamping face, is transversely continuous across the clamping face to extend from a left surface and to a right surface of the clamping portion, and is disposed near the intersection of the bottom surface and the clamping face. 10. The clamp of claim 9 wherein at least a portion of the lower gripping element has a flat face portion parallel with the clamping face. 11. The clamp of claim 10 further comprising an upper gripping element that is perpendicular with the clamping face, wherein the upper gripping element extends outwardly from the clamping face and is transversely continuous across the clamping face to extend from a left surface and to a right surface of the clamping portion. 12. The clamp of claim 11 and wherein the upper gripping element includes a cross section that includes a substantially pointed portion. 13. The clamp of claim 11 wherein the upper gripping element has a general cross section of an ogee having one of either a curved upper section or an angled upper section, and wherein the ogee protrudes from the clamping face and wherein the upper gripping element protrudes perpendicularly from the clamping face."
