The locking mechanism has associated therewith a spring biased locking pin carried by the clamp body for holding the locking mechanism in the closed jaw position and a handle operable from the clamp body exterior to shift such mechanism, such handle carrying a manually engagable push button disposed to be engagable with the locking pin to release the locking mechanism from the closed jaw position.
