A floor panel having the form of a plank and/or tile and being made of a plastic material for producing a floor covering or similar, said panel comprising at least two pairs of opposing sides defining two adjacent edges comprising male coupling means and two opposing adjacent edges comprising female coupling means, the kinematic assembly of these panels being vertical; - the male coupling means are formed of at least one so-called proximal groove opening onto a lower face of the panel and of a flexible distal tongue extending from the end of the edge of the panel towards the lower face of said panel, - the female coupling means are formed of at least one proximal groove opening onto an upper face of the panel and of a flexible tongue extending from the end of the edge of the panel, towards the upper face of said panel, - the deformable flexible distal tongue of the male coupling means has a proximal wall inclined at an angle β with respect to a vertical plane towards the bottom and towards the outside of the panel, - the flexible tongue of the female coupling means has a proximal wall inclined at an angle α with respect to a vertical plane towards the top and towards the outside of the panel, - the distal tongue (5, 7) of at least one of the male coupling means or female coupling means has a distal wall comprising, at least, a protrusion or a notch that is able to engage with a notch or a protrusion formed in or on a proximal wall of the proximal groove (6, 4) of the corresponding female coupling means or male coupling means so as to form an end stop, avoiding vertical movement of a panel with respect to an adjacent panel, characterized in that the flexible tongue of the female coupling means comprises a chamfered part forming an angle of between 2° and 20° with respect to the main plane of the panel, wherein said chamfered part gives rise to a reduction in the clipping force and to a deformation of the flexible tongue such that it is easier to assemble two adjacent panels., and in that: - the distal wall and the proximal wall of the deformable flexible distal tongue of the male coupling means are parallel and inclined towards the bottom and the outside of the panel at an angle β with respect to a vertical plane; - the proximal wall of the flexible distal tongue of the female coupling means and the proximal wall of the proximal groove of the female coupling means are parallel and inclined towards the top and towards the outside of the panel at an angle α with respect to a vertical plane; - the angle α is equal to the angle β and is comprised between 1° and 45°. - the male coupling means are formed of at least one so-called proximal groove opening onto a lower face of the panel and of a flexible distal tongue extending from the end of the edge of the panel towards the lower face of said panel, - the female coupling means are formed of at least one proximal groove opening onto an upper face of the panel and of a flexible tongue extending from the end of the edge of the panel, towards the upper face of said panel, - the deformable flexible distal tongue of the male coupling means has a proximal wall inclined at an angle β with respect to a vertical plane towards the bottom and towards the outside of the panel, - the flexible tongue of the female coupling means has a proximal wall inclined at an angle α with respect to a vertical plane towards the top and towards the outside of the panel, - the distal tongue (5, 7) of at least one of the male coupling means or female coupling means has a distal wall comprising, at least, a protrusion or a notch that is able to engage with a notch or a protrusion formed in or on a proximal wall of the proximal groove (6, 4) of the corresponding female coupling means or male coupling means so as to form an end stop, avoiding vertical movement of a panel with respect to an adjacent panel, characterized in that the flexible tongue of the female coupling means comprises a chamfered part forming an angle of between 2° and 20° with respect to the main plane of the panel, wherein said chamfered part gives rise to a reduction in the clipping force and to a deformation of the flexible tongue such that it is easier to assemble two adjacent panels., and in that: - the distal wall and the proximal wall of the deformable flexible distal tongue of the male coupling means are parallel and inclined towards the bottom and the outside of the panel at an angle β with respect to a vertical plane; - the proximal wall of the flexible distal tongue of the female coupling means and the proximal wall of the proximal groove of the female coupling means are parallel and inclined towards the top and towards the outside of the panel at an angle α with respect to a vertical plane; - the angle α is equal to the angle β and is comprised between 1° and 45°.
