A wind deflector has a bearing base and a shiftable body that is shiftable relative to the bearing base between a first, extended position, in which the body is spaced apart from the bearing base and a second, placed-on position, in which the body is placed onto the bearing base. Two spaced apart links extend between the body and the bearing base. Each link has one end articulated to the body and a second end articulated to the bearing base. A push-push lock is provided for fixing at least one of the link and the body in the placed-on position of the body.
