Abstract
A pair of locking tongs for grasping items which includes two arms, each with a hinge end and a grasping end. A hinge pin is provided for pivotally connecting the two arms together at their hinge ends so that the arms can pivot between an open and closed position. A locking plate is provided for locking the arms in the closed position slidably disposed at the hinge ends of the arms. The locking plate is movable from a first unlocked position to a second locked position whereby the locking plate engages the hinged ends of the arms and prevents the arms from opening.
