Abstract
A toy building set comprising box-shaped building elements that have, in the horizontal plane, dimensions that are integer multiples of a horizontal module (L), and, in the vertical direction, a height (H) which exceeds the horizontal module. The building elements have a tubular opening at a first face. Elements are provided that have a tenon that can be introduced into the tubular opening. At its free end, the tenon is flexible and has protruding edges ( ) for snap-effect with the second end of the tubular opening, and the tenon has a protruding portion ( ) that serves to ensure that the tenon can be introduced only so deeply into the tubular as corresponds to the horizontal module (L). The building set comprises building elements ( ) with coupling studs ( ) on the top face and a cavity ( ) with a tubular coupling means ( ), whereby two such elements are able to interconnect with coupling studs ( ) in contact with the sides of the cavity ( ) and the tubular member ( ). The tube has internal edges ( ) whereby a tenon can be introduced into the tubular member with snap-effect with the internal edge in the tube.
