Connecting element for joining of building elements, such as boards, plates or the like together on the both sides of the connecting element for forming a double-sided construction, such as a sandwich-construction, comprises holding surfaces (5) on its opposite sides, the holding surfaces being interconnected by a connecting portion. The holding surfaces (5) are provided with spikes, nails, prongs or the like (6) projecting from the surfaces and acting as means for attaching the building elements on opposite sides of the connecting element. The opposite sides of the connecting element are each constituted of a separate element (1), which is joined to the opposite element by means of a joining piece (2) for forming the said connecting portion between the holding surfaces (5). |
