A structural section (2) of a tower crane consisting of latticework with vertical beams (10), crosspieces (11) and diagonals (12) with an attachment joint comprising a coupling (1) for coupling to a contiguous structural section (2'). Said coupling (1) comprises a flat base (3) fixed to a connection block (4) welded at the end of each vertical beam (10) of the structural section (2), the flat base (3) covering a perimeter of the projection of said connection block (4).At least two ends of the connection block (4) protruding with respect to the projection of the vertical beam (10). Each of said ends of the connection block (4) comprises a through hole for the introduction of a screw for attachment with a connection block (4') of the contiguous structural section (2'). The flat surface of the flat base (3) of a structural section (2) remains in the assembly position in direct contact with the flat base (3') of the adjacent structural section (2').
