COUPLING SYSTEM

摘要

The invention relates to a coupling system (12) which is used to connect a tube (7) to a socket (8). Said tube (7) comprises a support (13) which is arranged on at least one of the ends thereof. Said support can be inserted into the socket (8) and the comprises, on the external side thereof, at least one annular groove (14) and a securing contour (16). The socket (8) comprises a stop contour (20) on the external side thereof. A coupling element (17), which is produced separately in relation to the socket (8) and the support (13), is placed on the outside on the support (13). The coupling element (17) comprises at least one stop hook (19) which engages behind the stop contour (20) when the support (13) is inserted into the socket (8). The coupling element (17) comprises at least one securing hook (18) which co-operates with the securing contour (16) in order to fix the coupling element (17) to the support (13) in an axial manner.
