The invention concerns a hook for moving formwork elements with an infeed mouth for receiving a frame profile of concrete formwork elements. The hook comprises a rotatably mounted retaining latch. The retaining latch can be moved back and forth between a closing position and a receiving position. In the closing position, a frame profile, which is received by the infeed mouth and thereby hold, cannot leave the infeed mouth of the hook anymore. In the receiving position, a received frame profile can leave the infeed mouth and the hook can thereby be detached from the formwork. The hook comprises an attachment means in order to attach the retaining latch for example with a chain to a crane. The retaining latch can be moved from the receiving position to the closing position by means of loading the attachment means. It is object of the invention to develop such hook further such that in particular accident risks are minimized. The problem is solved by a pawl, by which the retaining latch is blocked when the retaining latch is located in the closing position.
