ABSTRACT:
A C-clamp and a wedge of an adapter for an excavating bucket have locking parts which substantially eliminate any tendency for the wedge to become loosened from a space between the C-clamp and a wedge block. Spring loaded teeth in the front surface of the C-clamp are received in corresponding notches in the juxtaposed rear surface of the wedge. As the wedge is driven into its operating position, the spring loaded teeth in the front of the C-clamp alternately move into and out of the adjacent notches until the wedge is tight and as the teeth are received in the notches, thus locking the wedge in place. The wedge is removed by driving the wedge block downwardly, shearing a shear pin, thereby allowing the wedge block, the wedge and the C-clamp to be separated from the adapter and fall to the ground.
