Sliding roof for vehicles having a cover which, in a closed position, covers a roof opening of a fixed roof surface, which cover is rearwardly slideable below or above the fixed roof surface. In the area of the front edge of the roof opening, there is a pivotably mounted wind deflector, which is tiltable into an upwardly extended position by sliding the cover back, and, by way of an actuating device, is tiltable back into a retracted position when the cover is moved forward. In addition to the elements of the actuating device, there are provided two locking elements, bilaterally attached to the wind deflector, against which, in the foremost sliding position of the cover, there is contact by hold down clamping elements, which are displaceable together with the cover.
