L'unité de corps destinée à un dispositif de génération d'aérosol consiste : en un mécanisme de liaison rotatif qui relie la première unité et la seconde unité en conséquence d'une projection de mise en prise qui est fournie à l'une parmi la première unité et la seconde unité étant insérée dans une rainure de mise en prise qui est disposée dans l'autre et étant mise en rotation dans un premier sens de rotation autour de l'axe central de l'unité de corps ; en une première partie saillante qui est disposée sur l'une parmi la première unité et la seconde unité et qui fait saillie vers l'extérieur dans un sens radial qui est orthogonal à l'axe central ; et en une seconde partie saillante qui est disposée sur l'autre parmi la première unité et la seconde unité et fait saillie vers l'intérieur dans le sens radial. Lorsque la liaison est réalisée par le mécanisme de liaison rotative, au moins l'une parmi la première saillie et la seconde saillie se déforme élastiquement dans le sens radial, passe sur l'autre et se verrouille sur l'autre dans un second sens de rotation qui est opposé au premier sens de rotation.
