The present invention relates to an artificial contractile device comprising at least one contractile element (1) comprising a flexible strip (4) extending in a longitudinal direction and a closure (6) for forming the contractile element (1) into a closed loop around a hollow body organ, the closure (6) being situated at a first extremity of the flexible strip (4). The contractile element is adapted to contract a hollow body organ, in such a way that said contractile element (1) may be in a resting position or in an activated position. The artificial contractile device further comprises a flexible transmission (3) comprising a tensioning element (31) being anchored at a first end (311) to a first anchoring point (A) on the flexible strip (4), said flexible transmission (3) being adapted to tighten the contractile element (1) formed in a closed loop around said hollow body organ upon application of a traction force at and end of the tensioning element (2031) by an actuator (7). The artificial contractile device also comprises a connector (5) adapted to connect the flexible transmission (3) to a said actuator (7), a second end (312) of said tensioning element (2031) being anchored in said connector (5).La présente invention concerne un dispositif contractile artificiel comprenant au moins un élément contractile (1) comprenant une bande flexible (4) s'étendant dans une direction longitudinale et une fermeture (6) pour former l'élément contractile (1) en une boucle fermée autour d'un organe corporel creux, la fermeture (6) étant située au niveau d'une première extrémité de la bande flexible (4). L'élément contractile est conçu pour contracter un organe corporel creux, de telle sorte que ledit élément contractile (1) peut être dans une position de repos ou dans une position activée. Le dispositif contractile artificiel comprend en outre une transmission flexible (3) comprenant un élément de tension (31) qui est ancré à une première extrémité (311) à un premier point d'an
