Date Apr. 1, 1993.Known sets of structural elements have blocks with depressions and cross-shaped, T-shaped or Z-shaped connecting pieces which come to be located therein. Only retaining walls which are oriented in a straight line can be constructed. The set of structural elements according to the invention has, in addition to blocks with depressions, coupling pieces with at least a part thereof being in the form of a truncated cone, with corresponding cross-sectional shape of the depression.
