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 the female coupling means (3) comprise two complementary notches (5) and/or lugs (4) forming, after assembly of two adjacent panels (1), stoppers against a vertical displacement between two assembled adjacent panels (1).
