A top hood for a truck comprises a hood body having an opening, a curtain secured at its leading end to the margin of the opening and coextending with the opening, and two pairs of slide fastener stringers, each pair having an inner and an outer stringer tape each carrying a fastener element row along their respective inner longitudinal edge, the inner tape being secured along the respective marginal edges of the curtain and the outer tape along the respective marginal edges of the opening. A pair of bottom end stops are applied to the respective inner longitudinal edges of the inner and outer tapes at their trailing ends. A slider is threaded onto each pair of stringers to couple and uncouple the same. The slider has a lower wing and an upper wing provided with means for holding the trailing end portion of the element row carried on the inner tape. Further, the top hood comprises means for actuating the sliders to travel forwardly and backwardly along the respective pairs of element rows for engaging and disengaging the same.
