A floor panel includes male and female coupling means that are formed by at least one proximal groove that opens onto a lower face or upper face, respectively, of the panel and by a distal flexible tongue that extends from the end of the edge of the panel towards the lower face or upper face, respectively. The tongue has a proximal wall inclined at an angle with respect to a vertical plane towards the bottom and the outside of the panel and towards the top and the outside of the panel, respectively. The tongue of at least one of the male coupling means or female coupling means has a distal wall that includes, 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 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. The flexible tongue of the female coupling means comprises a chamfered part that forms an angle of between 2° and 20° with respect to the main plane of the panel.
