An inverted T profile for forming false ceiling support structures, consisting of a central web (4) which extends from an upper tube (6) and terminates in two horizontal flanges (8), characterised in that each end of the web comprises a drawn seat (10) which extends into a lip (12) to define a aperture (14), each end of the web extending into a substantially rectangular tab (16) having the same height as the aperture (14) and as the drawn seat (10), said tab comprising a non-rectilinear cut (20) which forms a tooth (22) projecting from the plane of the tab towards the drawn seat (10), the articulation axis of said tooth being non transverse to the longitudinal axis of the web, the tooth (22) of a first profile being engagable by the edge (26) of the aperture (14) of a second adjacent profile when the tab (16) of said first profile is inserted into the drawn seat (10) of the adjacent second profile and vice versa. |
