Abstract
A toy building set of building elements (10, 30) having coupling studs (15) and cavities (34) to receive coupling studs (15) in frictional engagement. The cavity (34) accommodates guide means (37) which are adapted to contact coupling studs (15) with a lower friction, and which thereby preferably have a guiding function. This ensures that small and large toy building elements may be built together with a desired coupling force and with a desired friction.
