4. The case ( 1 ) according to claim 3 , wherein said second opening ( 81 ) of said conveying duct ( 8 ) comprises two diffusion flaps ( 82 ) internal to said duct for distributing the air flow in a uniform way on said transparent panel ( 5 ).

5. The case ( 1 ) according to claim 3 , wherein at said second opening ( 81 ) said first body part ( 91 ) comprises a diffusion flap ( 83 ) tilted with respect to the transparent panel ( 5 ).

6. The case ( 1 ) according to claim 1 , wherein said holding device ( 9 ) comprises a fixing plate ( 96 ) for fixing said video camera ( 2 ) provided with at least a slotted hole ( 97 ) to be connected in an adjustable way with a positioning means ( 11 ) of said video camera ( 2 ).

7. The case ( 1 ) according to claim 6 , wherein said fixing plate ( 96 ) is made of metal and it is placed in contact with said means ( 6 ) heating said air flow.

8. A holding device ( 9 ) for a video camera ( 2 ) for use in a protection case ( 1 ), comprising

a body

air flow generating means ( 7 ) for generating an air flow,

at least one electronic unit for supplying and/or controlling the air flow generating means ( 7 ) for generating an air flow,

wherein the body of the device comprises a second housing ( 94 ) for the air flow generating means ( 7 ) for generating an air flow and a first housing for the electronic unit, and wherein the body comprises a first body part ( 91 ) and a second body part ( 92 ) connectable to each other, wherein said first and second body parts are such that once connected they define at least one section of a conveying duct ( 8 ) for said air flow, said conveying duct ( 8 ) being defined by surrounding walls made of a heat insulating material, and extending between a first and a second end of said conveying duct ( 8 ), wherein said first end of said conveying duct ( 8 ) opens on the housing ( 94 ) for the air flow generating means ( 7 ) and wherein said second end of said conveying duct ( 8 ) faces an end of said body that is opposite to said first end of said conveying duct ( 8 ) where said housing ( 94 ) is positioned, wherein a second opening ( 81 ) of said conveying duct ( 8 ) comprises two diffusion flaps ( 82 ) internal to said conveying duct ( 8 ) for distributing the air flow in an uniform way on a transparent panel ( 5 ), and said first body part ( 91 ) comprises a diffusion flap ( 83 ) tilted with respect to the transparent panel ( 5 ).

9. The holding device ( 9 ) according to claim 8 , further comprising heating means ( 6 ) and a seat ( 95 ) for fixing a heating means ( 6 ), wherein said fixing seat ( 95 ) is made on said first body part ( 91 ) at one of said surrounding walls of said conveying duct ( 8 ), and wherein said seat is placed in a position proximal to said second end.

10. The holding device ( 9 ) according to claim 9 , comprising a metal fixing plate ( 96 ) provided with a slotted hole ( 97 ) adapted to receive a positioning means ( 11 ) of said video camera ( 2 ), said fixing plate being mounted at least partially above or in contact with said heating means ( 6 ), so that said air flow, comes in contact with the fixing plate ( 96 ).
