FIELD: light industry, in particular, manufacture of toys. SUBSTANCE: construction system has constructional members with through openings, connecting members including connecting threaded poles, and fastening devices adapted for cooperation with poles for joining of constructional members with one another. Fastening devices are made so that when screwed onto connecting poles, fastening devices tightly bias assembled constructional members to stop on respective connecting member. Fastening devices are made in the form of threaded connecting heads and connecting members are made in the form of triangular connecting frames equipped with stop surfaces and connecting poles perpendicularly protruding from respective stop surfaces to outside. EFFECT: simplified and flexible construction suitable for constructing of various articles. 12 cl, 12 dwg
