Abstract: A panel (1) having a blade or slab shape, preferably made of a plastic material for producing a floor or wall covering, said panel (1) comprising two pairs of opposite sides defining four edges, two edges of which comprise male coupling means (2), and two edges comprise complementary female coupling means (3), the kinematics of assembling of two adjacent panels (1) being vertical, characterized in that: the male coupling means (2) comprise two parallel grooves extending along the edge and opening onto a bottom face of the panel (1), so as to define an internal male groove (2a), an external male groove (2b), an internal male stud (2c), and an external male stud (2d); the female coupling means (3) comprise two parallel grooves extending along the edge and opening on an upper face of the panel (1), so as to define a female internal groove (3a), a female external groove (3b), a female internal stud (3c), and a female external stud (3d); the male coupling means (2) comprise two lugs (4) and/or notches (5) and t

Abstract: The invention relates to a panel in the form of a strip or tile for producing of a floor covering, the panel comprising two pairs of opposite sides defining—two opposite edges for the assembly at an angle, of which one edge comprises male coupling means provided from a side wall of the panel, and an opposite edge comprises complementary female coupling means provided from a side wall of the panel; two opposite edges for vertical assembly, of which one edge comprises a male coupling means provide provided from a bottom face of the panel, and an opposite edge comprises complementary female coupling mead provided from a top face of the panel. According to the invention, the male coupling means of the edges for vertical assembly comprise two parallel groves that extend along the edge and open onto a lower face of the panel so as to define an inner male groove.
