The invention relates to elements for creating space structures, which can be used in the creation of space structures for general and industrial purposes. The technical result of the proposed invention is the creation of a structural element that imparts robustness and a greater load bearing capacity to assembled structures, is workable during assembly and installation, allows the creation of structures having a variety of shapes, and provides for a low-weight structure following assembly. The claimed structural element consists of tension elements, linking elements, stiffening elements and connecting nodes. Two tension elements are each connected by their ends to at least than one stiffening element. All of the stiffening elements are joined to one another at the intersection of the longitudinal axes of the stiffening elements and/or with the aid of an additional connecting element consisting of one or more parts. The ends of the tension elements are connected to one another with the aid of the linking elements, the tension elements of the structural element being coplanar. A second embodiment of the structural element is also disclosed.
