    摘要: A fire-protection sleeve (1) for a pipe, cable and the like (T) has an axially extending tubular metal housing (2), which has a radially outwardly projecting connecting flange (3) at one end. An end section (6), at the one end of the housing (2), contains a heat-intumescing composition (10), formed on the inner wall of the housing (2) and surrounds the axis of an axially extending opening (9) in the tubular housing (2) for the pipe, cable and the like (T). At the end section (6) of the housing (2) having the heat-intumescing composition (10), metallic lamellas (12) are arranged, which extend radially inwardly into the opening (9) of the housing (2) for the pipe, cable or the like (T) and are flexible in the axial direction of the opening (9).
