PROBLEM TO BE SOLVED: To provide an attachment for a hydraulic shovel, of which the wearing parts can be easily exchanged at a low cost. SOLUTION: The one clamping part 27 for cracking and the other clamping part 28 are installed in a freely driving manner for opening/closing, and these clamping parts 27, 28 are welded with a plurality of attaching parts 32, 33 respectively. These attaching parts 32, 33 are detachably fitted with respective socketed pawls 34, 35, and the attaching parts 32, 33 are fixed to the socketed pawls 34, 35 by inserting pins 44, 63 into the attaching parts 32, 33 and the socketed pawls 34, 35 respectively. The pins 44, 63 are prevented from being pulled in such a way that the grooves formed on their peripheral surface are fitted to the retainers installed in the pawls 34, 35 in the freely inserting and extracting manner.
