A closure device for connecting two parts includes a first closure part which includes a first surface with an arrangement of first structure elements arranged thereon and a second closure part which includes a second surface with an arrangement of second structure elements arranged thereon. The first closure part and the second closure part are to be positioned together in such a manner that the first surface of the first closure part faces the second surface of the second closure part such that the first structure elements and the second structure elements engage in one another in such a manner that movement of the closure parts relative to one another along a load direction is blocked.
