A mechanical grasping device for retrieving dropped objects includes a pair of opposing claws and an extension element. The extension element may be either rigid or flexible, and is typically a rope or cord. A trigger plate is positioned between the two claws, and is spring loaded to transmit tension to the claws when the device is in the open position. A pair of protruding tabs at the end of the arms of the trigger plate are received in locking holes in the claws in an open position. When the triggering mechanism is released, the spring tension urges the claws together so that interlocking fingers on the ends of the claws mesh together in a closed position. The object to be retrieved is secured in the grasping device, and the user pulls the object to him using the extension element.
