Toy building set according to  claim 19 , wherein, in the member an end slot cut making the member at least partly hollow parallel to its plane is arranged in its opposite sides, and a halving cut directed towards the centre point of the member is arranged in the said cut sides. 
     
     
         21 . Toy building set according to  claim 20 , wherein the member is arranged to be a square, from each corner of which a piece is cut off. 
     
     
         22 . Toy building set according to  claim 16 , wherein the arms are connected to each other by means of a joint joining the shanks to each other and permitting rotational flexibility. 
     
     
         23 . Toy building set according to  claim 16 , wherein a lightening is arranged in the arm, in order to improve the rotational flexibility properties of the lugs. 
     
     
         24 . Toy building set according to  claim 16 , wherein the arms are straight at the ends of the connector. 
     
     
         25 . Toy building set according to  claim 16 , wherein, in the arm, there is
 a bevel arranged in the tip for the locking groove, and   a step arranged on the back side of the lug, which is arranged to correspond to the wall of the slot of the building block.   
     
     
         26 . Toy building set according to  claim 16 , wherein connector's
 half width is less than the depth of the slots in the building blocks,   length is at most the same as the length of the shorter side of the building block, and   thickness in the flexing direction is greater than the distance between the opposing locking recesses of the slot of the building block.   
     
     
         27 . Toy building set according to  claim 16 , the building blocks of which includes, in addition, triangular blocks, wherein at least some of the connectors belonging to the connector series are equipped with arms, on the back side of which are arranged guiding and alignment members for the lateral attachment of the triangular blocks to the other building blocks of the toy building set.
