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).
