The tire-pressure sensor articulating device includes a tire-inflation valve having a base which contacts to the cradle of an electronic unit (12). The electronic unit is pressed against the bottom of a rim (16) by tightening a securing nut onto the threaded part of the shank of the valve. The valve base is provided with a rough spherical portion collaborating with the cradle of the electronic unit.
