Abstract

The invention relates to a connection (7) of a fuel supply device in a motor vehicle, which is characterized in that a corrugated hose (5) is held in a peripheral groove (10) of a connection piece (8) by means of a glue (12) and in that the groove (10) protrudes from an undulation of the corrugated hose (5). The corrugated hose (5) can thus be connected to the connection piece (8) with very little effort. The connection (7) is also inexpensive to produce.

Claims

1. A connection, in particular a connection of a fuel supply device in a motor vehicle, for a corrugated hose on a connection piece, characterized in that the connection piece (8, 9, 18) has a peripheral groove (10, 17), and in that the corrugated hose (5, 16) is integrally fastened materially in the groove (10, 17).

2. The connection as claimed in claim 1, characterized in that the groove (10) is filled with adhesive (12).

3. The connection as claimed in claim 1 or 2, characterized in that an edge of the groove (17) is manufactured from a material which is permeable to a laser beam of an intended wavelength and the corrugated hose (16) is manufactured from a material which is impermeable to the laser beam.

4. The connection as claimed in claim 1, characterized in that the groove (10, 17) has means for retaining the corrugated hose (5, 16) in a positively locking manner.

5. The connection as claimed in claim 1, characterized in that the edge (11) which bounds the groove (10, 17) has a projection (13) which points radially inward.

6. The connection as claimed in claim 1, characterized in that the internal diameter of the groove (10, 17) is slightly larger than the internal diameter of the corrugated hose (5, 16).

7. The connection as claimed in claim 1, characterized in that the internal diameter of the groove (10, 17) is larger than the external diameter of the free end of the connection piece (8, 9, 18).

8. The connection as claimed in claim 1, characterized in that the edge (11) is elastic.

9. The connection as claimed in claim 1, characterized in that the groove (10, 17) is deeper than at least one corrugated section of the corrugated hose (5, 16).
