Fragmentable compression device for the anastomosis of hollow organs consisting of a pot-shaped body composed of two elements (1, 2), inserted one into the other and consisting of a plurality of composable sectors (5, 6), a third ring-shaped or hollow cylinder-shaped element (3) intended to be inserted into said pot-shaped body to clamp the edges of the organs to be anastomized, and a fourth element (4) also ring-shaped or hollow cylinder-shaped which is pressure-inserted into element (3) to compress said edges. Also elements (3, 4) consist of a plurality of composable sectors (7, 8). The axial dimension of the device is notably short so that, when it is applied in the vicinity of the anal canal of the patient, tenesmus is considerably reduced.
