The device of the invention can be used for covering the surface of a building and comprises at least two plates having different sizes made of a metal or plastic material and capable of being assembled. The first plate includes at least one side having an substantially Z shape while the opposite side has an inclined face, the second plate includes a side with a face inclined towards the inside at the same inclination as the central bar of the Z while the opposite side has an inclined face substantially identical to the first plate, and in that the two plates slide one within the other by said Z sides at the face inclined towards the inside on the one hand and at the face inclined towards the outside on the other hand. The two plates have a different size in a direction perpendicular to the inclined sides so that they can slide one within the other in a telescopic manner. |
