The enclosure (1) has bellows (2) extended along a reference axis (3) between an unfolded position in which the bellows has maximum length along the reference axis and a folded position in which the bellows has minimal length along the reference axis. A reinforcement is secured to the bellows, and includes foldable elongated elements (5) that are extended longitudinally. The elongated elements possess selected length, so that the elements are tightened when the bellows is in the unfolded position. Each of the elements has two ends secured to end flanges (6, 7). Independent claims are also included for the following: (1) a method for producing bellows for a separation enclosure (2) a particle detector. L'invention concerne une enceinte (1) de séparation entre deux espaces (62, 63) soumis à une différence de pression, l'enceinte (1) comportant un soufflet (2) s'étendant suivant un axe de référence (3), le soufflet (2) étant extensible entre une position dépliée dans laquelle il présente une longueur maximale suivant l'axe de référence (3) et une position repliée dans laquelle il présente une longueur minimale suivant l'axe de référence (3) et une armature (4) solidaire du soufflet (2), l'armature (4) comportant des éléments longiformes pliables (5) s'étendant longitudinalement, les éléments longiformes pliables (5) présentant une longueur choisie de façon à ce que qu'ils soient tendus lorsque le soufflet (2) est en position dépliée.
