Annular element (3) placed between the two beads (12) of a tyre P mounted on a flat-bottomed wheel rim (J). In order to be able to use the said tyre P on the said wheel rim J without adding an air chamber (inner tube), the annular element (3), in order to seal the assembly has, in meridian section, a contour, and in particular two lateral sides (30) such that the clamping s between the ring (3) and the beads (12), from nothing or even a negative value to the base of the ring (3) then increases slightly over a certain radial distance h1 then increases greatly over a distance h2 which is radially adjacent to the first distance.
