The invention relates to a cleaning device (20) for internal cleaning of drain or sewer pipes (30) comprising at least one chain (25) comprising several chain links (10), two end parts (22), to one of which one end of the chain/chains (25) is/are fastened and to another of which another end of the chain/chains (25) is fastened, which end parts (22) each comprise a central opening (24), through which a rotatable element (27) extends. At least some of the chain links (10) of at least one chain (25) of the cleaning device (20) have substantially rectangular outer form having at least one right-angled corner (13) and that these chain links (10) are of hard metal. The invention also relates to a method of manufacturing a chain for the cleaning device, in which the chain links (10) are made by cutting from a hard metal plate, for example by laser cutting.
