Description

BRIEF DESCRIPTION OF THE FIGURES

[0030] Further features, details and advantages of the disclosure are disclosed in the wording of the clams and in the following description of exemplary embodiments, with reference to the drawings, in which:

[0031] FIG. 1 shows an embodiment of a clip,

[0032] FIG. 2 shows an alternative embodiment of a clip,

[0033] FIG. 3a shows a cross section of a clip,

[0034] FIG. 3b shows a cross section of an alternative clip,

[0035] FIG. 3c shows a cross section of an alternative clip,

[0036] FIG. 3d shows a cross section of an alternative clip.

DETAILED DESCRIPTION

[0037] FIG. 1 shows a clip 1 according to an embodiment with a clip band 2, which has a base 3 and two radially inwardly directed flanks 4. In the embodiment shown here, the clip band 2 has a trapezoidal profile. The clip 1 has an inner face 5 which is formed by the inner face of the base 3 and the flanks 4, and an outer face 6 which is formed by the outer face of the base 3 and the flanks 4. The ends 7 of the clip band 2 are connected together, clamped and fastened via a clamping device 8. In the example shown here the clamping device 8 has a screw with a screw head and a screw connection. The outer face 6 of the clip 1 has a thermal insulation layer 9 which in this case covers both the flanks 4 and the base 3. Here the thermal insulation layer is a non-positive coating of the outer face 6 of the clip 1.

[0038] The embodiment shown in FIG. 1 has two clip portions 10, 11 which are connected together via a joint portion 12.

[0039] In FIG. 2 an alternative embodiment of the clip is shown. The clip 1 has a cover band 13 which is connected to a radially external surface of the clip band 2. A material connection is produced by means of welding. The clip band 2 has three clip portions 10, 11, 14.

[0040] Since the cover band 13 forms the outer face 6 of the clip 1, this cover band is at least partially coated with a thermal insulation layer 9. For example, the thermal insulation layer 9 consists of a ceramic material. Neither the ends 7 of the clip band 2 with the clamping device 8 nor the inner face 5 of the clip 1 have this thermal insulation layer 9.

[0041] In order to permit a simple production of the clip 1 with a thermal insulation layer 9 on the outer face 6 of the clip 1, it may also be provided that in addition to the cover band 13 the respective outer face 15 of the flanks 4 of the clip band also has a thermal insulation layer 9. Additionally, the free regions of the radially internal surface 16 of the cover band 13 and the lateral surfaces 17 of the cover band 13 may also be coated with the thermal insulation layer 9. These features are not shown here.

[0042] FIGS. 3a to 3d show cross sections of clips 1. The profile of the clip 1 is shown here as a trapezoidal profile. The embodiments shown by way of example, however, are able to be transferred to any other profile of a clip 1.

[0043] FIG. 3a shows a cross section of a clip 1 with a thermal insulation layer 9 on the outer face 6 of the clip 1, in this case exclusively the outer face 18 of the base 3 is coated.

[0044] FIG. 3b shows a cross section of a clip 1 with a thermal insulation layer 9 on the outer face 18 of the base 3 and the outer face 15 of the flanks 4. This embodiment is able to be produced in a particularly simple and cost-effective manner.

[0045] FIG. 3c shows a cross section of a clip 1 with a thermal insulation layer 9 on the outer face 6 of the clip 1, wherein the outer face 6 of the clip 1 is formed by the cover band 13. In the embodiment shown here, exclusively the radially external surface 19 of the cover band 13 has a thermal insulation layer 9.

[0046] FIG. 3d also shows a cross section of a clip 1 with a thermal insulation layer 9 on the outer face 6 of the clip 1. Here in addition to the radially external surface 19 of the cover band 13, the free regions of the radially internal surface 16 of the cover band 13, the lateral surfaces 17 of the cover band 13 and the two outer faces of the flanks 4 are also coated with a thermal insulation layer 9.

[0047] The invention is not limited to one of the embodiments described above but is able to be modified in many different ways.

[0048] All of the features and advantages disclosed in the claims, the description and the drawings, including structural details, spatial arrangements and method steps, may be essential to the invention both per se and also in very different combinations.
