1. A panel having a shape of a plank or a tile for a production of a floor covering, the panel comprising two pairs of opposed sides defining:
two opposed edges configured for inclined assembly, wherein one edge comprises male coupling means provided from a lateral wall of the panel, and an opposed edge comprising complementary female coupling means provided from a lateral wall of the panel;
two opposed edges configured for vertical assembly, wherein one edge comprises male coupling means provided from a lower face of the panel, and an opposed edge comprising complementary female coupling means provided from an upper face of the panel;
wherein:
the male coupling means of the edges for vertical assembly comprise a male groove extending along the edge and opening onto the lower face of the panel in a manner to define a male tenon, the male tenon having an outer wall that is inclined with respect to a vertical plane and towards the outside of the panel;
the female coupling means of the edges for vertical assembly comprise a female groove extending along the edge and opening onto the upper face of the panel in a manner to define a female tenon;
the male coupling means of the edges for vertical assembly comprise a male groove extending along the edge and opening onto the lower face of the panel in a manner to define a male tenon, the male tenon having an outer wall inclined with respect to a vertical plane and towards the panel and an inner wall inclined with respect to said vertical plane and towards the panel at the same angle as the outer wall.
