         19 . A fan device for being inserted without pressure in an opening of a wall, the wall having a wall front side and a wall rear side, the opening connecting the wall front side and the wall rear side, the fan device comprising:
 a fan front side proximal to the wall front side; a locking element for fastening the fan device in the opening of the wall;   wherein the locking element is displaceable in a mounting direction from the wall front side to the wall rear side; wherein the locking element is mounted to be actuatable from the fan front side;   wherein the locking element comprises a tongue, the tongue comprising a wedge-shaped tensioning hook, the tongue being formed straight and being linearly displaceable in the mounting direction.   
     
     
         20 . The fan device of  claim 19 ,
 further comprising a housing;   wherein the locking element is movable to the housing and is manually displaceable from a mounting position into a fixing position, the locking element being in the fixing position when the fan device fixed onto the wall, the locking device being in the mounting position when the fan device is inserted in the opening of the wall.   
     
     
         21 . The fan device of  claim 20 ,
 wherein in the fixing position the locking element engages the rear side of the wall.   
     
     
         22 . The fan device of  claim 19 ,
 further comprising a housing;   wherein the locking element is disposed through the housing, the locking element being displaceable relative to the housing.   
     
     
         23 . The fan device of  claim 19 ,
 wherein the locking element is disposed in an inner edge region of the fan device.   
     
     
         24 . The fan device of  claim 19 ,
 wherein the locking element is disposed in a side region of the fan carrier.   
     
     
         25 . The fan device of  claim 19 ,
 wherein the locking element is stepless for locking the fan device to a plurality of thicknesses of the wall.   
     
     
         26 . The fan device of  claim 19 ,
 wherein the locking element comprises a plurality of latching positions for locking the fan device to a plurality of thicknesses of the wall.   
     
     
         27 . The fan device of  claim 19 ,
 further comprising a guide device, the guide device determining a movement direction of the locking element.   
     
     
         28 . The fan device of  claim 19 ,
 wherein the locking element is displaceable in a locking direction, the locking direction being opposite to the mounting direction.   
     
     
         29 . The fan device of  claim 19 ,
 further comprising a fan carrier;   wherein the locking element is disposed in at least a corner of the fan carrier.
