<p>The bar (1) which forms the frame of the collector has a lower recess (8) and an upper recess (9), intended to house some extensions (10) of a protective bar (11) which is coupled collaterally to the bar (1), and which hides on its interior accessory elements of the collector, and also it is possible to couple a covering bar (13) which is introduced in the upper recess (9) of bars (1) belonging to different collectors to cover the space separating collectors. Also the bar (1) incorporates a screw (16) in its base between the head (20) of which and a nut (18) a space is defined which facilitates the guided displacement of the bar (1) in a sliding manner with respect to a guide bar (21) up to its final securing, which guide bar (21) is attached to a base bar (22) which constitutes an adjusting and positioning element of the collector with respect to the roof.
