A TOY BUILDING ELEMENT AND A METHOD AND A MOLD FOR PRODUCING SUCH A TOY BUILDING ELEMENT FOR A TOY BUILDING SET

A toy building element having an integrally injection molded body comprising at least two adjacent tubular connector sockets (1, 2) and two mutually equidis- tant connecting flanges (7, 8) extending from diametrically opposite sides of one of the two adjacent tubular connector sockets (1) and to diametrically opposite sides of the other one of the two adjacent tubular connector sockets (2) so that a first channel is formed (10) between them. The first channel (10) extend be- tween the two parallel surfaces (5, 6) and a first stiffening wall (9) is arranged in the first channel (10), the first stiffening wall (9) dividing the first channel (10) into a first channel part close to one of the two parallel surfaces (5) and a second channel part close to the other of the two parallel surfaces (6), and wherein at least a section of the first stiffening wall (9) is closer to one of the two parallel surfaces (5) than it is to the other one of the two parallel surfaces (6).
