The lower part at the bottom has gripping means for engaging a gripping tool which, in turn, has gripping means for engaging a fuel element or a control rod. The lower part of the body has a power operable device for each of the gripping means and each power operable device is spring urged toward coupling position. A locking device pivotally mounted in the lower part of the body is actuated into locking position by upward movement of the upper part on the lower part and when in locking position locks the power operable device in coupling position.</p> |
