摘要

The fluidic device (1) has a support structure formed by a support ring which is unbroken in the circumferential direction and adjoins the base section of a fastening element (15). A ring-form retaining tooth concentrically encompasses the support ring and is installed on the support ring's end section facing away from the base section and engages with positive locking in an unslotted section of the wall (8) of the circular cylindrical longitudinal section of a recess (3).
