A holding device with a securing sheet for mounting onto a wall. The device comprises a base means and a holding means connected with said base means for supporting a foreign article. An impervious securing sheet is connectable air-tightly onto the wall and extends outwardly beyond a backside of the base means. A friction plate is connected to the base means and the securing sheet. If the friction plate and the securing sheet pull away from the wall, a negative pressure prevents the article from falling.
