Hooking and restraining structure for anchoring seal and back stop gaskets between sections and accessories for door- and window frames and the like made from extruded sections from aluminium and its alloys, constituted by a continuous channel-shaped seat, having a substantially U-shaped through-section, obtained on the sides and the flanges of an unusual section for door-and window frames and the like, and provided with a shaped flange running along the longitudinal edge of at least one of the flanges of said seat, the channel-shaped cavity of said seat being suitable to pressure-housing the peduncle or stem of a continuous gasket having the part outside the seat variously shaped, so as to provide a set of seal and back stop gaskets, said flanges protruding outwards of said seat constituting, on the contrary, as many means for the stable hooking of sections with other sections and/or accessories of door- and window frames and the like. <IMAGE>
