A section member specifically designed for rigidly assembling together structural elements of a seat, and more particularly an aircraft seat, by axial sliding and by mechanical clamping, the section member presenting in right cross-section a shape that is generally H-shaped with a single central web, or a shape that is hollow, being rectangular or pseudo-rectangular and having two generally analogous webs that are spaced apart from each other, and also having two respective pairs of flanges that are generally analogous to one another and that are spaced apart from one another, in opposing pairs on either side of the web, or a pair of flanges that are generally analogous to each other and spaced apart from each other, joining together the sides of the two webs, with the flanges having towards their free edges, respective projections extending at least towards the transverse midplane of the webs and serving to participate in guiding the axial sliding and the locking of the structural element.
