<p>CLAMP A spring steel wire is bent to have an open head from which criss-crossing limbs extend to form separated limbs each with two bearing points for gripping an object to be clamped. Preferably each limb is a tilted "L" which is normally crossed twice over the other limb. The head defines a hand or finger grip such that when the extremes of the separated limbs are placed in contact with a work to be clamped, the head affords a grip by which the entire clamp may be twisted with respect to the work and then pushed further onto the work such that the grip of the clamp on the work is increased because of the forces resulting from the re-orientation of the cross-over limbs.</p> |
