Claim Text:
1. A metal profile for a false ceiling, the metal profile including a main portion and an integral engaging member connected as a single body, or as one piece, to at least one end of the main portion, wherein said integral engaging member includes a plate portion and an engaging tongue or fin connected as one piece to the plate portion, wherein the metal profile is made of a steel strip or sheet metal of thickness equal to or lower than 0.25 mm, wherein the steel presents the following combination of features: maximum tensile strength Rm from 500 N/mm elongation from 2% to 8%, said engaging tongue or fin is detached or separated from said plate portion on two cut sides of said engaging tongue, the two cut sides of said engaging tongue with respect to the plate portion are adjacent and intersecting so as define a free edge or corner, the engaging tongue has one side connected to the plate portion, said side being a hinge side for both the cut sides of the engaging tongue so that the engaging tongue has a triangle shape: a first cut side of said two cut sides has a first free end and a second end connected to the hinge side and a second cut side of said two cut sides is located, with respect to the first cut side, further towards an inner or central zone of the metal profile and wherein the second cut side is intended to interfere with a counter-engaging edge of another metal profile in a engaged condition, said second cut side having a first free end defining with the first end of the first cut side said free edge or corner and a second end forming a second end of said hinge side; wherein said engaging tongue or fin is displaceable by means of elastic deformation between a first position in which the engaging fin is located in a rest condition protruding from a plane of the plate portion, and a second position in which said engaging fin is in a elastically deformed condition displaced towards the plane of the plate portion, and vice versa.
