1. A medium calibre fin-stabilised anti-air shell comprising:
a nose cone extended by a case tube and a central pin that delimits with the case tube a housing that encloses sub-projectiles, wherein the case tube is attached to the nose cone via an upstream thread, and the central pin and the nose cone are made of one piece;
a rear end cap that encloses an air burst charge;
a casing that covers the case tube, the casing being attached to a flange on the case tube via a downstream thread at a front end of the casing and the casing being attached onto the rear end cap via a thread at a rear end of the casing; and
translation means positioned between the rear end cap and the case tube so as to ensure a shearing of the upstream and downstream threads.
