An assembly kit has a hollow structural element having at least one groove inwardly of a face thereof and open to the hollow of this structural element, and a recess communicating with the groove and open at the face of this structural element. Another structural element is positionable on the first-mentioned hollow structural element and has another groove which is smaller than the groove of the hollow structural element. A connecting element is provided, which has one portion insertable in the one groove of the hollow structural element, and another portion insertable in the other groove of the other structural element so as to connect the above structural elements with one another. The connecting element has also a third portion insertable in the recess of the hollow structural element so as to prevent the connecting element from moving inwardly of the hollow of the hollow structural element. |
