    FASTENING DEVICE FOR ATTACHING AN AIR GUIDING DEVICE TO AVEHICLE BODY TECHNICAL FIELD The invention relates to a fastening device for attaching an air guiding deviceto a vehicle body. The invention also relates to a vehicle.
    BACKGROUND ART Vehicles travelling through air will force aside the air affecting the fuelconsumption of the vehicle. Vehicles such as trucks with a leading vehiclebody and a trailing vehicle body are commonly provided with an air guidingdevice supported by the leading vehicle body in order to reduce the airresistance.
    Such a trailing vehicle body is often replaceable and the dimensions mayvary, requiring adjustment of the air guiding device for optimal reduction ofthe air resistance.
    The air guiding device is provided with a front hinge element fixedly attachedon rail element by means of fastening device in the form of T-screwsvertically arranged and configured to run in the rail element.
    A problem with such a mounting solution is that the air guiding device isdifficult to assemble, the air guiding device being a relatively heavy and bulkyarticle which needs to be correctly positioned prior to being tightened by means of the screws.
    This mounting procedure is time consuming and difficult.
    OBJECTS OF THE INVENTION An object of the present invention is to provide a fastening device forattaching an air guiding device to a vehicle body which facilitates easy andefficient mounting of an air guiding device to a vehicle body of a vehicle.
    SUMMARY OF THE INVENTION These and other objects, apparent from the following description, areachieved by a fastening device and a vehicle which are of the type stated byway of introduction and which in addition exhibits the features recited in thecharacterising clause of the appended independent claims. Preferredembodiments of the fastening device are defined in appended dependent claims.

The trailer 4 is coupledto the tractor 2 and is exchangeable, wherein height and width of the trailer 4may vary.
    The vehicle 1 may also be constituted by a vehicle where the second vehiclebody 4 is a fixed trailing vehicle body arranged to be fixedly connected to thefirst vehicle body 2.
    A pair of rail elements 40, 50 are running in the longitudinal extension on theroof 2a of the first vehicle body 2. The pair of rail elements 40, 50 comprisesa right rail element 40 running in the area of the right side of the roof 2a anda left rail element 50 running in the area of the left side of the roof 2a. The left and right rail elements are parallel and run at a distance from each other.
    The air guiding device 10 arranged on the roof 2a is arranged to be fastenedby means of a fastening device I to the respective rail element 40, 50. Thus,a left side of the air guiding device is arranged to be attached to the left railelement 50 by means of a fastening device I and the right side of the air guiding device is arranged to be attached to the right rai| element 40 bymeans of a fastening device l.
    The respective fastening device I is according to an embodiment slidinglyarranged on the respective rai| element 40, 50. The air guiding device 10 isthus movably arranged along the rai| elements. The air guiding device isaccording to an embodiment movably arranged between a transport positiona position adapted for a fixed trailing vehicle body and a position adapted fora trailer.
    The vehicle 1 may also be provided with a first side air guiding device 20arranged on one side 2b and a second side air guiding device 30 arrangedon the opposite side 2c of the first vehicle body 2 as illustrated in fig. 1b.Each air guiding device 10, 20, 30 is arranged to be supported by means ofsaid first vehicle body.
    Each air guiding device 10, 20, 30 is adjustable relative to said longitudinalaxis X for air resistance reducing purposes. Each air guiding device 10, 20,30 is arranged to direct air which during drive is forced aside by the vehicle inan air resistance reducing way. The air guiding device 10 comprises an air guiding element 12.
    The air guiding device 10 is adjustable by means of pivoting about an axis Yrunning in the transversal extension, i.e. width extension, of the vehicle andperpendicular to the longitudinal axis X in connection to the front end of the air guiding element.
    Fig. 2 schematically illustrates a perspective view of a hinge element 60provided with at clip member 70 according to an embodiment of the presentinvention. The hinge element 60 and the clip member 70 are comprised in afastening device 1 according to the present invention, the fastening devicebeing shown in fig. 3 and 4.
    The hinge element 60 is configured to be pivotally attached to the vehiclebody of a vehicle for pivoting said air guiding device about an axis Y foradjustment relative to said longitudinal axis.
    The hinge element 60 comprises an attachment element 62 for attaching theair guiding device. The attachment element 62 has a flat sheet-shapedportion 63 or sheet portion 63 with through holes 63a, 63b, 63c, 63d evenlydistributed for receiving screw elements for attaching the air guiding device.The attachment element 62 is arranged to pivot about the axis Y foradjustment of the air guiding device.

    The clip member 70 is configured to be pivotally arranged about the axle 66of said hinge element 60. As can be seen in fig. 5, the clip member 70 has ahollow pipe portion 72 for receiving the axle 66. The pipe portion 72 has aside portion 72a configured to face the vehicle body when mounted and anopposing side portion 72b configured to face away from the vehicle body.The pipe portion 72 thus has a through hole 72c. The clip member 70 comprises a pair of opposing resilient leg members 73, 74, i.e. a first legmember 73 and a second leg member 74, extending from the pipe portion 72in a direction away from the vehicle body in a mounted state.
    The opposing resilient leg members 73, 74 are extending away from eachother in a non-biased state. The opposing resilient leg members 73, 74 areresilient such that when pressed against each other they a spring force actsoutwardly for returning the opposing leg members 73, 74 to their non-biasedposition.
    The opposing resilient leg members 73, 74 have substantially flat endportions 73b, 74b shown in fig. 2.
    The clip member 70 and hence the pipe portion 72 has an axial extensionbeing shorter than the distance between the opposing leg members 64, 65 ofthe hinge element 60. The clip member 70 is thus configured to be arrangedbetween the opposing leg portions 64, 65 of the hinge element 60, the axle66 being introduced through the through holes 64a, 65a of the opposing legportions 64, 65 and the hollow pipe portion 72 of the clip member. The clipmember 70 is thus configured to be pivotally arranged about the axle 66 of said hinge element 60.
