A B S T R A C T A reinforcing bar for stiffening and guiding a flexible curtain in a vertically raisable door is fixed horizontally to said curtain and each of its ends penetrates into a corres- ponding vertical guiding slideway (1). At each of its ends, the bar includes a zone of reduced mechanical strength such as to enable the bar to escape from the guideways (1) when it is subjected to a thrust of given force substantially perpendicu- larly to the curtain (2). The bar is constituted, for example, by a tubular portion (3) having two protective end pieces (43) fitted to its respective ends, with said end pieces being designed to break at zones of weakness (433).
