<p>A constructional toy comprising a first element (10) and a second element (12). The first element (10) has a first engagement surface (14) and a first engagement feature (16) located adjacent the first engagement surface (14). The second element (12) has a second engagement surface (24) and a second engagement feature (26) located adjacent the first engagement surface (24). The engagement feature (16,26) are configured such that the act of urging the engagement feature (16,26) of one element (10,12) into engagement with the engagement feature (16,26) of the other element (10,12) biases the engagement surfaces (14,24) into frictional engagement with one another.</p> |
