Abstract (en)
A system, and an angular element used in it, are described, for the mutual fixing of sections (1,2) of a duct for conveying air, wherein the adjacent ends (3) of two sections (1,2) have projections and/or recesses (14A,14B) which cooperate for defining an engagement seat wherein at least a portion (18,18',19) of a structural joining element (4) has to be inserted. According to the invention, said adjacent ends (3) have a portion (16) which is apt for realizing the external coverage of the coupling area between said projections and/or recesses (14A,14B) and the portion (18,18',19) of said structural joining element (4) inserted in said seat. Moreover, said structural joining element (4) is realized for allowing its easy insertion and/or removal in parallel direction with respect to a ceiling and a wall, when the canalization is placed next to a wall and a ceiling. <IMAGE>
