EMBODIMENTS OF THE INVENTION

[0019] As is apparent from FIGS. 1 to 6, the represented exemplary embodiments of a fastening device 1 according to the invention for a line (3), in particular for an electric cable, in a vehicle, comprise in each case a carrier 20 which encloses line 3 and has a multi-part base body 22 with at least two partial base bodies 22A, 22B which can be separated at least partially from one another in such a manner that an inner region of base body 22, in a premounted state, can be placed around line 3 and which can be connected to one another in such a manner that base body 22 of carrier 20, in a mounted state, encloses line 3 in a fully annular manner. A fixing structure 26 which, in the mounted state, axially fixes carrier 20 on line 3 is formed according to the invention on the inner region of base body 22. In this case, a fastening element 10, 10A has a fastening structure 19, 19A and a holder 12, 12A which connects fastening element 10, 10A detachably and radially movably to carrier 20.

[0020] As is further apparent from FIG. 3, fixing structure 26 is, in the represented exemplary embodiment, formed as a rib structure with a radially running rib and several axially running ribs which, in the mounted state, generate at least one recess in the casing of line 3. Base body 22 of carrier 20 or the ribs thus have at least a greater hardness than the casing of line 3 in order to generate the recesses in the line casing for fixing of carrier 20. Base body 22 of carrier 20 is preferably manufactured as an injection molded part made of a plastic, such as, for example, a polyamide (PA6.6) which has good rigidity, hardness, abrasion resistance and dimensional stability under heat. Other suitable plastics for producing base body 22 can of course also be used.

[0021] As a result of this rib structure, base body 22 of carrier 20 is fixed axially and radially on line 3. In the case of an exemplary embodiment which is not represented, fixing structure 26 embodied as a rib structure comprises at least one radially running rib in order to fix carrier 20 axially on line 3. Base body 22 of carrier 20 comprises, in the exemplary embodiment represented, two semi-circular partial base bodies 22A, 22B which, in the premounted state, are connected to one another in each case along a side edge via an integrated joint 28.3. In the represented exemplary embodiment, joint 28.3 is embodied as a plastic skin. Alternatively, joint 28.3 can be embodied, for example, as a hinge or tension spring. Partial base bodies 22A, 22B which are connected to one another on a side edge can be easily placed around line 3 via the open side edges. On the in each case open side edge, partial base bodies 22A, 22B can be connected to one another via a mechanical connection 28. Mechanical connection 28 is, in the represented exemplary embodiment, embodied as a form-fitting clip connection with corresponding interacting connecting contours 28.1, 28.2 which can be pushed into one another so that base body 22 of carrier 20 encloses line 3, in the mounted state, in a fully annular manner. In the represented exemplary embodiment, a first partial base body 22A comprises a first connecting contour 28.1 which is embodied as a lug and which interacts in a latching manner with a corresponding second connecting contour 28.2, embodied as a latching recess, of a second partial base body 22B.

[0022] As is further apparent from FIG. 2, a first holding structure 24 is formed on the outer circumference of base body 22. In the represented exemplary embodiment, first holding structure is formed as a circumferential annular recess with a U-shaped cross-section which is arranged approximately centrally on base body 22.

[0023] As is further apparent from FIGS. 1, 4 and 6, fastening structures 19, 19A of the represented exemplary embodiments of fastening element 10, 10A are embodied in each case as pine tree clips which can be clipped into a corresponding fastening opening, not represented, in the vehicle body. Of course, the fastening structures can also have another suitable form in order to be fastened on the vehicle body. Holders 12, 12A of the represented exemplary embodiments of fastening element 10, 10A have in each case a base body 14, 14A with a round inner region which, in the mounted state, at least partially encloses carrier 20. Moreover, a second holding structure 16, 16A is formed on the inner region of base body 14, 14A which, in the mounted state, engages in first holding structure 24 of carrier 20, In the case of the represented exemplary embodiments, second holding structure 16, 16A is formed in each case as a radial rib.

[0024] As is further apparent from FIGS. 4 and 5, holder 12 has, in the represented exemplary embodiment, a spring-elastic C-shaped base body 14 which clips onto base body 22 of carrier 20 and is guided radially movably. Second holding structure 16 embodied as a radial rib is arranged centrally on the inner region of base body 14 and engages, in the mounted state, into first holding structure 24 embodied as an annular recess. As a result, an axial movement of fastening element 10 can be advantageously prevented, while a radial movement of fastening element 10 is furthermore possible and fastening element 10 can be rotated into the desired radial position. As a result of spring-elastic C-shaped base body 14, base body 14 of holder 12 can be pushed onto base body 22 of the carrier or pulled from it via the opening with a defined expenditure of force.

[0025] As is furthermore apparent from FIG. 6, holder 12A has, in the represented exemplary embodiment, a multi-part base body 14A with at least two partial base bodies 14.1A, 14.2A. Partial base bodies 14.1A, 14.2A can be separated from one another at least partially such that base body 14A of holder 12A, in a premounted state, can be placed with its inner region around base body 22 of carrier 20. Partial base bodies 14.1A, 14.2A can furthermore be connected to one another in such a manner that base body 14A of holder 12A, in a mounted state, encloses base body 22 of carrier 20 in a fully annular manner.

[0026] As is furthermore apparent from FIG. 6, base body 14A of holder 12 has, in the represented exemplary embodiment, two partial base bodies 14.1A, 14.2A which have in each case a semi-circular inner region on which second holding structure 16A embodied as a radial rib is arranged approximately centrally. Partial base bodies 14.1A, 14.2A of base body 14A are, in the represented premounted state, connected to one another in each case along a side edge via an integrated joint 18.3A. In the represented exemplary embodiment, joint 18.3A is embodied as a plastic skin. Alternatively, joint 18.3 can be embodied, for example, as a hinge or tension spring. Partial base bodies 14.1A, 14.2A connected to one another on a side edge can be easily placed around base body 22 of carrier 20 via the open side edges so that holding structure 16A embodied as a radial rib can engage in first holding structure 24 embodied as an annular recess. Partial base bodies 14.1A, 14.2A can be connected to one another via a form-fitting connection 18A at the in each case open side edge. Form-fitting connection 18A is, in the represented exemplary embodiment, embodied as a clip connection with corresponding interacting connecting contours 18.1A, 18.2A which can be pushed into one another so that base body 14A of holder 12A encloses base body 22 of carrier 20 in a fully annular manner. In the represented exemplary embodiment, a first partial base body 14.1A of holder 12A comprises a first connecting contour 28.1 which is embodied as a latching recess and which interacts in a latching manner with a corresponding second connection contour 28.2, embodied as a lug, of a second partial base body 14.2A of holder 12A.
