A clamp comprising:
- a first arcuate portion;
- a second arcuate portion hingedly connected to the first arcuate portion;
- and
- a ratchet mechanism for locking the first and second arcuate portions in a closed position;
- wherein the ratchet mechanism comprises a linear rack provided with the second arcuate portion and a pawl provided with the first arcuate portion for receiving the linear rack;
- wherein the linear rack comprises a plurality of toothed paths each comprising one or more asymmetrical teeth;
- wherein the pawl comprises a plurality of fingers which are biased into engagement with the teeth of the linear rack;
- wherein each of the plurality of fingers are configured to engage with the teeth of one of the plurality of toothed paths;
- characterized in that:
- a first path of the plurality of toothed paths comprises one or more teeth having a larger height than the teeth of a second path of the plurality of toothed paths, wherein the teeth of the first path are positioned so as to provide tactile/audible feedback to a user to indicate an optimum clamping force.
