A folding pushchair has a chassis provided on each side with two chassis struts (6,7) carrying wheels (8). The struts are pivotally connected together, and swing out of a folded position, in which they lie side by side, into a position of use, in which they are secured by means of a fastening device (14). This device has to swing upwards to release the struts but a seat, and hence the weight of a child in the pushchair bears down on the device (14), thereby avoiding accidental folding in use.
