摘要

The multi-channel tube (1) has an outer tube (10), where an insert element (20) is inserted in an inner chamber (10') for forming two passage channels (2). The insert element has projections (24a to 24c). One of multiple recesses (13a to 13c) of an outer pipe forms a press fit (15a to 15c) together with one of the projections of the insert element. An independent claim is also included for a method for manufacturing a multi-channel tube.
