Abstract
An end piece (1) for a tubular heater (2) has an insulator (10) traversed from the end portion (8) by its connecting member (6) in a passage (16) and substantially completely closing the associated end portion (7) of tube casing (3) and on whose end face (19) remote from the tubular heater (2) is provided a separate metal connecting piece (20) welded to the associated end face of connecting member (6) by a welding head (33). Connecting piece (20) forms one or more freely projecting elements (25) for direct connection to electrical leads. Thus, end piece (1) is positively secured with respect to the tubular heater (2) and is suitable for an easy electrical connection, which can be released at any time.
