Profile for connecting one or more panellings to a building element, said profile comprising: - a bottom capable of being anchored to an installation surface of said building element - a first and second wing, opposed and substantially parallel to each other, between said wings (11, 12) and said bottom there being defined a cavity that serves as a seat for at least the base of said one or more panellings, - locking means adapted to retain said one or more panellings in a set-up co-planar to the median plane (β-β) of said profile, said locking means also serving as adjusting means of the inclination of said one or more panellings with respect to said median plane, said adjusting means comprising: - at least a first and second actuator: - capable of translating crosswise inside said cavity of said profile and of cooperating with a face (21; 22) of said one or more panellings, said first and second actuator being substantially located on one of said wings (11; 12) of said profile at a distance H from each other so as to determine at least one distal actuator and at least one proximal actuator relative to said bottom, - at least one fulcrum substantially located at one abutment element of the other wing (11; 12), cooperating with the other face (21; 22) of said one or more panellings, said fulcrum being in an intermediate position between said distal and proximal actuators the translation of said actuators (40, 41) enabling, inside the cavity of said profile, the rotation around said fulcrum of at least said base of said one or more panellings, wherein said proximal actuator comprises at least: - an adjusting element capable of translating crosswise inside said cavity of said profile and of cooperating with one face (21; 22) of said one or more panellings, - a drive means of said adjusting element: - manoeuvrable from the outside with specific manoeuvring tools, - comprising a manoeuvring interface for said tools located in the proximity of a distal zone of said cavity of said profile, characterised in that - said at least one adjusting element comprises at least one adjusting wedge capable of sliding on a sliding plane of a chute constrained and/or integral with one of said wings (11; 12) of the profile; - said driving means comprises an adjusting screw capable of being screwed/unscrewed on said chute and of acting on said wedge to allow the sliding thereof along said sliding plane. - a bottom capable of being anchored to an installation surface of said building element - a first and second wing, opposed and substantially parallel to each other, between said wings (11, 12) and said bottom there being defined a cavity that serves as a seat for at least the base of said one or more panellings, - locking means adapted to retain said one or more panellings in a set-up co-planar to the median plane (β-β) of said profile, said locking means also serving as adjusting means of the inclination of said one or more panellings with respect to said median plane, - at least a first and second actuator: - capable of translating crosswise inside said cavity of said profile and of cooperating with a face (21;
