<p num="1"><br/><br/><br/>The invention relates to device (1; 1'') for closing a natural or artificial <br/>anus, comprising an inflatable balloon (2) with an approximately toroidal <br/>structure made from a flat tube section, which is turned inside out and whose <br/>both ends (7, 8) extend coaxially into one another and are each joined to a <br/>sleeve (9). The outer layer (5) of the tube section that is turned inside out <br/>has a radially enlarged, patient-proximal area (3) for inserting into the <br/>rectum and has a patient-distal area (11, 7, 8), which is tapered thereto and <br/>which remains, at least in areas, outside of the rectum during use. The tube <br/>sections have, in the transanal area (11, 7, 8), a material hardness H1 of <br/>greater than 60 according to Shore hardness test A. According to the <br/>invention, a stiffening sleeve (14) is placed inside the interrectal area (3) <br/>of the inner layer (5) in such a manner that this sleeve is completely <br/>separated from the hollow space (10) inside the balloon (2) by its inner <br/>penetrable layer (5).<br/>
