Suspended ceiling system, suspended ceiling and use of the suspended ceiling system to make the ceiling suspended

The suspended ceiling (1) comprising a wire hanger (3) for suspending the suspended ceiling (2) and a rail (6) with a suspension opening (5), the wire hanger (3) comprising a hook 4 of suspension in an end part (8) of the wire hanger (3) to hook in the suspension opening (5) of the rail (6) of the suspended ceiling (2), the suspension hook (4) comprising an end part abutment (7), in which the suspension opening (5) receives the butt end portion (7) of the suspension hook (4) with the suspension hook (4) partially protruding through the opening (5 ) of suspension with the butted end part (7) and the opposite end part (8) of the suspension hook (4) placed on opposite sides of the suspension opening (5), in which the wire hanger (3) comprises a vertical part (9) adjacent to the end part (8) of the wire hanger (3), the rail (6) when hooked to the wire hanger (3) in the suspension opening (5) which is placed between the butt end portion (7) and the vertical portion (9), an extended portion (10) of the suspension hook (4) between the butt end portion (7) and the vertical portion (9) protruding through the suspension opening (5), in which the butt end portion (7) and the suspension opening (5) are provided in such a way that the suspension opening (5) is provided to receive the butt end portion ( 7) of the suspension hook (4) with a rotation movement (11) with a rotation axis (12) that extends along the vertical part (9) in which the largest cross section of the end part butt (7) extending along a plane substantially parallel to the suspension opening (5) overlaps with at least part of the rail (6) surrounding the suspension opening (5) when the vertical part (9 ) is positioned substantially along the direction of gravity and the rail (6) is substantially horizontal, for each position of the extended part (10) that protrudes substantially perpendicularly through the suspension opening (5) characterized because the rail (6) is a T-shaped rail (6) comprising a bead (14) along the upper edge of its vertical band and the extended part (10) has a length of at least half of the width of the bead (14) of the rail (6) and that the length of the extended part protrudes through the suspension opening and the dimensions of the butt end part are adapted in such a way that the butt end part does not extends substantially beyond the bead when mounted on the rail.
