The invention relates to a device for preventing incontinence comprising a fastening apparatus for stationary implantation in body tissue wherein a tubular body (3) has a first elongated guiding element (5 105) in the interior of the tubular body and a hose like retaining element is connected to the tubular body (3) the hose like retaining element having a second elongated guiding element (13) in the interior of the hose like retaining element the second elongated guiding element opening into a termination in the axial direction on the side of the second elongated guiding element opposite the tubular body (3). The first elongated guiding element (5 105) comprises the fastening apparatus in that the first elongated guiding element defines regions having projections (7) axially displaced from each other wherein the projections (7) are designed as slits (23) in the unexpanded state. After the first guiding element (5 105) is compressed in the axial direction said slits outwardly leave the surface of the guiding element and are erected in order to form the finished projections.
