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 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 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; where: - 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 such as to define a male tenon, the male tenon having an inner wall which is inclined with respect to a vertical plane and towards the outside of the panel, and at an angle of between 1° and 15°; - 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 such as to define a female tenon; - the male coupling means of the edges for vertical assembly comprise a lug or a notch and the female coupling means of the edges for vertical assembly comprise a complementary notch or lug which, after assembly of two adjacent panels, form abutment stops to counteract a vertical displacement between two adjacent assembled panels; Characterised in that the male tenon comprises also a outer wall which is inclined with respect to a vertical plane and towards the outside of the panel, and at an angle of between 1° and 15. - two opposed edges 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 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; where: - 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 such as to define a male tenon, the male tenon having an inner wall which is inclined with respect to a vertical plane and towards the outside of the panel, and at an angle of between 1° and 15°; - 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 such as to define a female tenon; - the male coupling means of the edges for vertical assembly comprise a lug or a notch and the female coupling means of the edges for vertical assembly comprise a complementary notch or lug which, after assembly of two adjacent panels, form abutment stops to counteract a vertical displacement between two adjacent assembled panels; - 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 such as to define a male tenon, the male tenon having an inner wall which is inclined with respect to a vertical plane and towards the outside of the panel, and at an angle of between 1° and 15°; - 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 such as to define a female tenon; - the male coupling means of the edges for vertical assembly comprise a lug or a notch and the female coupling means of the edges for vertical assembly comprise a complementary notch or lug which, after assembly of two adjacent panels, form abutment stops to counteract a vertical displacement between two adjacent assembled panels;
