Carriage which consists of a plastic, U-shaped component with a weakened line at its base, with one of its arms equipped with an internally hollow projection which receives another projection from its other arm, receiving, between both arms, the body of the window via a hole or drill hole of the latter. This component is equipped on the outside with projections or recesses for its sitting in an entrainment carriage, as a function of whether the window has one or two drill holes in correspondence with tabs of the carriages. <IMAGE>
