Angular wall profile

1. A suspended ceiling comprising an angular profile (1, 11, 21, 31, 41) comprising a first erect or vertical wing (2) extending in the longitudinal direction of the angular wall profile and comprising connecting means having the shape of a hole (10) to receive a screw, which connect the angular profile (1, 11, 21, 31, 41) of wall to a wall, the angular profile (1, 11, 21, 31, 41) being of wall connected to the wall by the connection means (10) such that the first erect wing (2) extends along the wall, further comprising the angular profile (1, 11, 21, 31, 41) of wall a first flange (5) that supports at least one ceiling plate (8), the first flange (5) being connected to the first erect wing (2) and pointing outwards of the first erect wing (2), comprising in addition the first erect wing (2) at least one perforation (9) essentially C-shaped to form a first part in the first erect wing (2) that is movable with respect to a second part remaining in the first erect wing (2), characterized in that at least the perforation (9) encloses the connection means (10) and because the connection means (10) are located in the first part of the first erect wing (2) such that when fixing the profile to the wall, said first part in the first erect wing (2) will move with respect to the second part in the first erect wing (2) when it finds a ripple and as such it will compensate for the undulations in the wall surface to which it is fixed.
