A plastic door (1) is made from rigid plastic panels (3, 3a) that hingedly secure to one another by a lateral slide interlock at adjacent edges of the panels. The panels (3, 3a) are foldable at the interlock between a first panel position in which the panels (3, 3a) are out of alignment with one another and a second panel position in which the panels (3, 3a) are aligned with one another. The slide interlock has sufficient play to enable release and connection of the interlock when the panels (3, 3a) are in the first panel position. One of the panel edges has a flex member (11) which acts to form a weather seal between the panel edges and to also tighten the slide interlock to the extent that the play within the interlock is eliminated to block any lateral movement between the panels when the panels (3, 3a) are in the second panel position.
