• the one-piece part 10 is shown in solid lines when it is in its initial undistorted configuration.
• the piece 10 makes it possible, in the absence of mechanical strain stress, to form a connection between two substantially parallel but non-coplanar surfaces S1, S2, and thus makes it possible to make up a maximum level difference.
• the elastic deformation of the one-piece piece 10, represented by dashed lines in FIG. 36 in one piece 10, makes it possible to increase the internal angle ⁇ between the two wings 101 and 102 and to form a connection between two substantially parallel surfaces S1, S2 and coplanar (zero level gap between the two surfaces), or between two substantially parallel and non-coplanar surfaces S1, S2 with a difference in level (E1, E2) between the two surfaces S1, S2, which is smaller than the difference between maximum level E in itiai referred to above corresponding to the initial configuration at rest of the part 10 in the absence of mechanical stress deformation.
• the invention is not limited to making a finishing connection between the floor and a floor covering or between two floor coverings, but can also be applied to make other types of finishing accessories suitable for forming finishing joints between two surfaces, such as skirting boards, cornices, picture rails, stair nosings.
