The load-transferring connecting element is adapted for transfer of force between the first and second building elements. The load-transferring connecting element includes an elongated box-shaped main body. A first end portion of the load-transferring connecting element is arranged for attachment into the first building element with a remaining second end portion of the load-transferring connecting element positioned so as to project from the first building element. The second end portion is adapted for being received in a cavity arranged in the second building element. The second end portion of the load-transferring connecting element is provided with an attachment area for attaching lifting equipment for handling of the first building element.
