• the present invention relates to an air conditioning duct comprising textile tube having an inlet end for an air intake from an air conditioning duct and an outlet end for an air output, wherein the inlet end is adapted to be attached to a wall of the air conditioning duct and is provided with and adjustment element.
• Air conditioning ducts for distribution of air are known in the art. These ducts may be made of metal or textile and are provided with openings for passing the distributed air from ducts to its surrounding.
• said openings can be provided with nozzles.
• the nozzles for air conditioning ducts so far known in the art have a strictly defined shape and thus also the direction of the air output. Therefore, during the use, they do not allow for change of the direction of the air.
• nozzles with an adjustable output direction which are provided with four spaced apart tunnels, wherein each of foe tunnels extends from the inlet end of the nozzle to the outlet end of the nozzle and comprises a tightening band within, wherein the tightening band is attached on one side and exits the tunnel on foe other side, are known in the art. It is therefore possible to adjust the length of foe nozzle on one of its sides by sliding the tunnel along the band, thus bending it to a desired direction.
• the drawback of these adjustable nozzles is that the adjustment is slow and difficult, because the tunnels decrease the flexibility of the nozzle.
• a nozzle for an air conditioning duct which comprises an inlet opening for air intake from an air conditioning duct at the inlet end, and an outlet opening for air output at the outlet end, the nozzle being adapted for being attached to the wall of the air conditioning duct by the inlet end and comprising on its external side a proximal annular circumferential area at the inlet end and a distal annular circumferential area, disposed spaced apart from the proximal area, at the outlet end, wherein the distal annular circumferential area is provided with an adjustment element, which is disposed outside of the nozzle and is fastened or fastenable to the proximal circumferential area and fastened or fastenab!e to the distal circumferential area, and is adapted for an adjustment and locking of the degree of tilting of the nozzle outlet end plane with respect to the nozzle inlet end plane by an adjustment of the length of the adjustment element between its fastening location to the circumfer
• the proximal circumferential area is provided with a set of proximal fastening elements for fastening of the adjustment element and/or the distal circumferential area is provided with a set of distal fastening elements for attaching the adjustment element, wherein the proximal fastening elements are made up of a set of loops, through which the annular reinforcement passes.
• the proximal fastening elements and/or the distal fastening elements are made up of annular band with loops and an annular reinforcement, which passes through the loops.
• the nozzle is preferably provided with an end piece having a cross- section, the size of which is decreasing in the direction from the inlet end to the outlet end.
• the distal area is arranged between the proximal area and the end piece.
• the distal area is preferably provided with an annular reinforcement and/or the proximal area is provided with an annular reinforcement.
• the adjustment element can be fastenable to at least one of the reinforcements for an adjustment and locking of the degree of tilting of the nozzle outlet end plane with respect to the nozzle inlet end plane.

• the nozzle comprises a cylindrical tube which has an inlet end 1, by which the nozzle is attached to the wall of the air conditioning duct 10 in such a way that it lines up with a through-hole in said wall.
• the duct has an outlet end, to which an end piece 3 is connected, the end piece having a truncated cone surface shape.
• the inlet end 1 of the tube is reinforced by means of an annular reinforcement 4, which is in tiiis exemplifying embodiment placed (removably) in a tunnel.
• the air conditioning duct may be made of metal or preferably textile.
• the nozzle is made of a flexible material, preferably textile, for example from the same material as the wall 10 of the textile air conditioning duct.
• the nozzle wall comprises a proximal area, wherein the nozzle wall " is provided on the external side with a set of three spaced apart proximal fastening elements 5.
• the nozzle wall comprises a distal area, where it is provided at the external side with a set of three spaced apart distal fastening elements

• the proximal fastening elements 5 do not have to be present.
• the outlet end is reinforced with an annular reinforcement 4 arranged on the external side of the nozzle and attached to the nozzle using three loops, with which they together form distal fastening elements 6.
• the adjustment element 7 passes through one of the proximal fastening elements 5 and an opposite distal fastening element 6, and the length of the adjustment element 7 is set in such a way that it pulls the fastening elements towards each other, thus directing the nozzle outlet opening in the desired direction.
• the nozzle is therefore bent to the side, to which the adjustment element 7 is attached.
• the loops in the proximal area are replaced with openings in the external side of the nozzle wall in the area of the annular reinforcement
