ABSTRACT:
A toy construction element comprises a rectangular wall formed with an apron whose edge defines a plane parallel to the wall. A plurality of parallel tubes arranged in a regular array pass through the base wall. The one end of each tube extending through the base wall has a predetermined inner diameter. The other end of each tube lies substantially at the level of the plane defined by the apron and has an outer diameter corresponding generally to the inner diameter. In addition this other end of each tube is cleft and is stepped between an outer region at the plane whose outer diameter corresponds to the inner diameter of the one end and an inner region of slightly greater diameter. Thus two such blocks can be fitted together with the other ends of the tubes of one block fitting into the one ends of the tubes of the other block, the skirt of the one block coming to rest on the wall of the other block.
