Device with at least one hollow element for conveying a fluid with a connection element

摘要

In an apparatus having at least one first hollow element for conducting a fluid having a connection element, to enable and facilitate a simple and reliable connection to a second hollow element, a snap-in element of the connection element having a latching surface which contacts an abutment surface in a connection state with the second hollow element is made as a radially widenable snap-in ring.

主权项

1. An apparatus having at least one first hollow element for conducting a fluid and having a connection piece which has a deformable snap-in element having a latching surface which contacts an abutment surface connected to a second hollow element in a connection state, wherein the latching surface and the abutment surface are configured as sealing surfaces which permanently exert axial pressure against each other in the connection state to establish axial sealing, wherein the snap-in element is a radially widenable snap-in ring which can be radially outwardly beaded over other parts of the connection piece, wherein the connection piece has a weakening of a wall of the connection piece in an axially bounded region, wherein the weakening is configured as an inwardly or outwardly facing peripheral groove in the wall of the connection piece, wherein the groove of the connection piece is configured for beading over the snap-in ring at the groove, wherein a wall thickness of the connection piece at the groove is less than a wall thickness of the snap-in ring.
