Abstract: A hose assembly for directing conditioned air from an air outlet vent of a vehicle's air conditioning system to various locations within the vehicle. The hose assembly comprises a boot which is selectively attachable to the vent, and a length of hose selectively attachable to the boot. The length of hose is divided into interconnecting segments which are selectively attachable to one another, thereby allowing a user to vary the overall length of the hose as desired. The terminal segment of the hose has a louver having a plurality of slats, and a handle in mechanical contact with the slats. Rotation of the handle changes the direction in which the slats point, and thereby allows the user to direct the conditioned air in any desired direction. The terminal segment has a mounting clamp for selectively attaching the hose to a projecting surface on the inside of the vehicle, in order to immobilize the hose at an optimal position.
