摘要

Connecting unit comprises a receiving bushing on a connecting part, and a connecting support for introducing into the bushing and on a filter candle or filter insert. A casing surface of the connecting support has a flattened area and a locking recess displaced in the peripheral direction. Connecting unit comprises a receiving bushing (1) fixed on a connecting part, and a connecting support for introducing into the bushing and on a filter candle or filter insert. A casing surface of the connecting support has a flattened area and a locking recess displaced in the peripheral direction. A cylindrical casing surface (4) of the bushing has a recess (5). A tensioning element (2) interacts with the recess of the casing surface of the bushing, and protrudes into the locking recess of the connecting support when assembled with the filter candle or filter insert. The connecting support is axial fixed relative to the bushing and the tensioning element reacts to the rotation of the connecting support. An independent claim is also included for a filter candle or insert.
