摘要

Casing for a filter cartridge including a cylindrical vessel (7) capable of being screwed onto a carrier which may receive a removable lid (8). According to the invention the vessel comprises a noncontinuous internal flange (17) and the lid has studs (19) which interact with this flange to prevent a rotation of the lid. A locking ring (22) partially covers the lid and comprises an internal edge (26) which has indentations (27) into which are clipped resilient hooks (21) of the lid and each of which comprises two notches (29) at their ends to receive the hook while defining two marked angular positions of the ring in relation to the lid, namely a locked position where the ring retains the lid on the vessel and an unlocked position where the said ring releases the lid. <IMAGE>
