A control device for an artificial sphincter for a natural bodily passage, in particular a urinary passage, which contains a variable volume envelope. The control device includes a first chamber in the form of a balloon, a second chamber defined by two plates joined by a membrane forming a bellows, between which the balloon is accommodated, and an elastic return mechanism including at least one elastic band around the plates.
