ABSTRACT:
A locking device is formed of a base, a grabbing member and a plurality of arcuate legs flexibly connecting the base and grabbing member. The grabbing member is operatively deformable by relative movement of the base and grabbing member toward and/or away from relative coplanarity therebetween to thereby expand or contract the grabbing member into or out of releasable locking engagement with a workpiece.
