Abstract: A toothed disk for fastening a feedthrough-plug-connected media line. The toothed disk includes a circular insertion opening that is defined at a periphery of the insertion opening by elastic holding teeth, separated from each other by respective slots. In the axial direction, the holding teeth extend at an angle to a longitudinal axis that is perpendicular the plane of the insertion opening. Each holding tooth is connected to an outer mounting section by at least one connecting web. Punch-outs are formed between the connecting webs. A mounting section is arranged on a peripheral circle around the insertion opening and lies in a plane parallel to the plane of the insertion opening. Each holding tooth is connected to the mounting section by at least two connecting webs. Also provided is a connection assembly for the feedthrough plug connection of a media line including the toothed disk.

Abstract: A coupling element of a plug connection for tubing includes a retaining screw with an inner passage opening. The inner passage has a bearing shoulder on which a retaining element is arranged and behind which a sealing element is mounted. A sleeve-shaped spacing element is arranged between the retaining element and the sealing element, and the retaining element is axially held between the spacing element and a bearing shoulder of the inner passage opening. The sleeve-shaped spacing element has an axial length such that a restriction in the diameter of the wall of the inserted tube, produced when the retaining element is under load, is bridged by the spacing element such that the annular sealing element abuts against an undeformed area of the tube wall.
