French term or phrase:dispositif anti-degondage
From a technical spex:
Les sorties de secours strictement nécessaires à l'exploitation du local seront équipées de portes métalliques. Portes avec dormants en cornière, vantaux double peau avec isolation, dispositif anti-dégondage.
I went with this one as it was less specific. Although security pins and dog bolts are types of unhinging mechanism, they may not be the only ones, and the ST does not specify. 4 KudoZ points were awarded for this answer
