摘要

The insert unit (10) for an opening, in particular, in a pipe-shaped hollow component comprises a flexible sealing element (40) which in its application position next to the flange (32) of the insert element (26) expands radially when subjected to an axial force by means of the tightening element (46). The latter is secured against unintentional displacement in the direction relieving the force on the flexible sealing element.
