An element (10) composed of a plurality of horizontally and vertically running strips (12 to 26) which have common intersection points, strips (12 to 26) being in each case closed rings (28), and in each case a ring (28) alternately surrounding the rings (28) arranged at right angles to it or being led through these rings(28), in each case a front end (36) of a ring (28) being led in each case through a rear end (38) of a ring (28) arranged at right angles to it, wherein the element (10) is a closed body with a square base area and a square basic element, ends (36;
- 38) projecting beyond the side edges (40) of rings (28) arranged at right angles to said ends, in such a way that eyes (42) or loops for mounting further elements or connecting elements (34) are obtained, so that the square basic elements can be joined to one another.
