摘要

The connecting element (1) is for fixing to a bag (2). It has a tube (6) extending into the bag. The connecting element has a clamping element (7) able to turn relative to the tube, with an internal thread (8) widening conically on the side facing the bag. This element can be turned to draw the bag material axially into the internal thread to form a reliable seal.
