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 (23) for snap-effect with the second end of the tubular opening, and the tenon has a protruding portion (21) 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 (30) with coupling studs (31) on the top face and a cavity (32) with a tubular coupling means (33), whereby two such elements are able to interconnect with coupling studs (31) in contact with the sides of the cavity (32) and the tubular member (33). The tube has internal edges (40, 42) whereby a tenon can be introduced into the tubular member with snap-effect with the internal edge in the tube.
