Abstract: In a connection apparatus for a corrugated tube a sealing sleeve, a coupling part, and an insertion part that can be inserted into the coupling part and comprises outwardly protruding latching portions on its outside surface, the coupling part is provided on an outside surface with cooperating latching portions. The coupling part comprises an inner holding device through which the corrugated tube can be guided in the direction towards the insertion part and performs elastically resilient radial movements thereby securing the corrugated tube against withdrawal. The corrugated tube extends into the sealing sleeve sitting in the interior of the insertion part having an axial flow passage, and with the holding device protruding axially into the opening of the insertion part in a coupled state. The outwardly protruding latching portions exposed on the outside of the connection apparatus when in the coupled state. The holding device compressing the sealing sleeve when in the coupled state.

Abstract: In a connection apparatus (1) for a corrugated tube (4) with a coupling part (2) and an insertion part (3) that can be inserted into the same and comprises on its outside jacket outwardly protruding latching cams (9) on its outside circumference, the coupling part (2) is provided on the outside with latching arms (5) which are radially outwardly deflectable, are attached according to the arrangement of the latching cams (9) on the insertion part (3), and each run over the respectively associated latching cams (9) during the axial insertion of the insertion part (3) into the coupling part (2) under elastic radial outward deflection and thereafter radially deflect inwardly again in a directly axial manner behind the latching cam (9). The coupling part (2) comprises an inner holding device (11) through which the corrugated tube (4) can be guided in the direction towards the insertion part (3) and performs elastically resilient radial movements thereby and secures the corrugated tube against withdrawal.
