A device for fastening a rollbar or similar attachment part on a vehicle, in particular a vibration roller, includes an inner installation sleeve, which is or can be operationally linked to a bar receptacle on the vehicle, an outer installation sleeve, which at least partially encloses the inner installation sleeve and is or can be operationally linked to the rollbar, and at least one elastomeric element, which positions the inner installation sleeve relative to the outer installation sleeve in such a way that the two sleeves are spaced apart from one another while partially forming a vibration clearance. In addition, the present invention relates to a rollbar or similar attachment parts for attachment on a vehicle, in particular on a vibration roller, having at least one device according to the above-mentioned type, which is implemented, in particular integrated on the rollbar.

1. A device for fastening a rollbar on a vehicle, comprising: an inner installation sleeve configured to be operationally linked to a bar receptacle on the vehicle, wherein the inner installation sleeve has a fastener receptacle in its sleeve interior, which is configured to be operationally linked
1. A device for fastening a rollbar on a vehicle, comprising: an inner installation sleeve configured to be operationally linked to a bar receptacle on the vehicle, wherein the inner installation sleeve has a fastener receptacle in its sleeve interior, which is configured to be operationally linked to a fastener on the bar receptacle;an outer installation sleeve at least partially enclosing the inner installation sleeve having an outer sleeve wall configured to be operationally linked to the rollbar, wherein the inner installation sleeve and the outer installation sleeve are arranged coaxially with respect to their respective longitudinal axes (AL); andat least one elastomeric element comprising an elastomeric sleeve which is situated between the inner installation sleeve and the outer installation sleeve, and positioning the inner installation sleeve relative to the outer installation sleeve in such a manner that the inner installation sleeve and the outer installation sleeve are spaced apart from one another and contact-free via a vibration clearance except in an area in which the inner installation sleeve and the outer installation sleeve are connected together via the at least one elastomeric element;wherein a subsection (a) along the longitudinal axes of the inner and outer installation sleeves along which the elastomeric element is situated is formed by a radial setback of an outer wall of the inner installation sleeve and a radial setback of an inner wall of the outer installation sleeve;the elastomeric element being configured to engage in a friction-locked manner in a recess formed by the setback of the outer wall of the inner installation sleeve and the setback of the inner wall of the outer installation sleeve such that the inner installation sleeve is positioned in a spaced manner with respect to the outer installation sleeve;the inner installation sleeve and the outer installation sleeve mutually having an intersection area (b), axially offset from the elastomeric element along the longitudinal axes of the inner and outer installation sleeves, which is configured to secure the inner installation sleeve and the outer installation sleeve in a location relative to one another;one of the inner installation sleeve or the outer installation sleeve having a radially protruding locking extension which engages into a radially set-back extension receptacle provided on the other of the inner installation sleeve or the outer installation sleeve to form the intersection area (b), with the locking extension and the extension receptacle being configured and situated in such a manner that the vibration clearance results between them such that the locking extension and the extension receptacle of the inner installation sleeve and the outer installation sleeve do not strike against one another in a case of normal vibrations, and striking only occurs, in a case of a failure of the friction lock by the elastomeric element or in a case of vibrations which exceed a normal oscillation curve, such that radial movement of the inner installation sleeve and the outer installation sleeve relative to one another is stopped by striking engagement of the locking extension and the extension receptacle. 2. The device according to claim 1, wherein the inner installation sleeve and the outer installation sleeve are implemented as rotationally-symmetric and coaxial to their respective longitudinal axis (AL). 3. The device according to claim 1, wherein the subsection (a) is formed by a peripheral recess on the outer wall of the inner installation sleeve and on the inner wall of the outer installation sleeve. 4. The device according to claim 1, wherein, to form the intersection area (b), the inner installation sleeve has the locking extension, which protrudes radially out of its outer sleeve wall, and the outer installation sleeve has the extension receptacle, which is radially set back into its inner sleeve wall, into which the locking extension protrudes while at least maintaining the vibration clearance. 5. The device according to claim 1, wherein the intersection area (b) and the subsection (a) are situated one behind the other in relation to the longitudinal axes (AL) of the inner installation sleeve and the outer installation sleeve. 6. An attachment part for attachment on a vehicle having at least one device according to claim 1. 7. The attachment part of claim 6, further comprising a vehicle, wherein the vehicle comprises a vibration roller. 8. The attachment part of claim 6, wherein the at least one device is integrated on a rollbar. 9. The device according to claim 1, further comprising an attachment part, wherein the attachment part comprises a rollbar. 10. The device of claim 1, further comprising a vehicle, wherein the vehicle comprises a vibration roller. 11. The device according to claim 1, wherein, to form the intersection area (b), the outer installation sleeve has the locking extension, which protrudes radially inward of its inner sleeve wall, and the inner installation sleeve has the extension receptacle, which is radially set back into its outer sleeve wall, into which the locking extension protrudes while at least maintaining the vibration clearance.
