A clamp (10, fig 1) includes a bar 120 and a jaw assembly (14, 16, fig 1). The jaw assembly receives the bar so that it is slidably positionable along the bar. The jaw assembly comprises a lever 114 that forms an aperture 118 through which the bar passes, the lever being movable between an engaged position (fig 3C) and a disengaged position within the jaw assembly (fig 3A). If the lever is in the disengaged position within the jaw assembly, the lever is slidable along the bar; and if the lever is in the engaged position within the jaw assembly, the lever engages the bar to hold the lever at a fixed position along the bar. The lever has a shape that is not substantially straight and reduces the positional difference between the engaged and disengaged positions. The lever may have an arcuate, hook shape. Alternatively, the lever may have first and second parallel tabs (140, 142, fig 4A), which are offset from one another. |
