Abstract
A toy building set of building elements ( ) having coupling studs ( ) and cavities ( ) to receive coupling studs ( ) in frictional engagement. The cavity ( ) accommodates guide means ( ) which are adapted to contact coupling studs ( ) 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.
