<p>A connecting device for tubular elements (1), in order to carrying out modular structures, includes: insert means (22) each having an expandable portion (2) and a head (3); shells (9) each provided with a plurality of housing (10) having a shape approximately complementary to the head (3); fixing means of head (3) to a related housing (10). In a locking condition of an insert mean (22) into an end of the tubular element (1), the expandable portion (2) is inserted into said end and it is expanded. In a connection condition of the tubular element (1) to the shell (9), the head (3) in the locking condition with the tubular element (1) is engaged in a related housing (10) of the shell and fixed to this latter by means of the fixing means.</p> |
