1. A male and female coupling means of a floor panel having the form of a plank and/or tile and being made of a plastic material for producing a floor covering, comprising:

  • the male coupling means being formed of at least one proximal groove intended to open onto a lower horizonal plane co-planar with a lower face of the panel and of a flexible distal tongue intended to extend from one end of one edge of the panel towards the lower horizontal plane co-planar with the lower face of said panel,the female coupling means being formed of at least one proximal groove intended to open onto an upper horizontal plane co-planar with an upper face of the panel and of a flexible distal tongue intended to extend from one end of an opposite edge of the panel, towards the upper horizontal plane co-planar with the upper face of said panel,the 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 of the panel and towards the outside of the panel,the flexible distal tongue of the female coupling means has a proximal wall inclined at an angle α

    with respect to a vertical plane towards the top of the panel and towards the outside of the panel,the flexible distal tongue 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 at least one proximal groove of the corresponding female coupling means or male coupling means of an adjacent panel so as to form an end stop, avoiding vertical movement of the panel with respect to the adjacent panel, whereinthe flexible distal tongue of the female coupling means comprises a chamfered part intended to form an angle of between 2° and

    20°

    with respect to the lower horizontal plane co-planar with the lower face of the panel, said chamfered part giving rise to a reduction in a clipping force and to a deformation of the flexible distal tongue such that it is easier to assemble two adjacent panels, and whereinthe distal wall of the flexible distal tongue of the female coupling means comprises an upper part inclined at an angle of between 1° and

    20°

    with respect to a vertical plane, and a lower part inclined at an angle of between 1° and

    20°

    with respect to a vertical plane, the upper part and the lower part extend parallel on either side of the protrusion or of the notch, and whereinthe proximal wall of the proximal groove of the male coupling means comprises an upper part inclined at an angle of between 1° and

    20°

    with respect to a vertical plane, and a lower part inclined at an angle of between 1° and

    20°

    with respect to a vertical plane, the upper part and the lower part extend parallel on either side of the notch or of the protrusion.
