       characterized in that:
 the locking/unlocking means ( 6 ) comprises a cam ( 6 A) which, by rotation, produces an elastic deformation of the inner frame ( 2 ), said produced elastic deformation enabling a releasing of the outer frame ( 3 ) from the inner frame ( 2 ). 
 
     
     
         2 . The swimming or diving mask according to  claim 1 , wherein at least one clipping means ( 7 ) located on said outer frame ( 3 ) is cooperating with at least one notch located on said inner frame ( 2 ) to secure the lenses ( 1 A, 1 B) between said outer frame ( 3 ) and said inner frame ( 2 ). 
     
     
         3 . The swimming or diving mask according to  claim 1 , wherein the locking/unlocking means ( 6 ) is located laterally from the inner frame ( 2 ) and laterally from the outer frame ( 3 ), on a periphery of said outer frame ( 3 ). 
     
     
         4 . The swimming or diving mask according to  claim 1 , wherein the outer frame ( 3 ) and inner frame ( 2 ) are made of plastic. 
     
     
         5 . The swimming or diving mask according to  claim 1 , wherein the outer frame ( 3 ) covers integrally the periphery of the outer surface ( 1 D) of the lenses ( 1 A, 1 B). 
     
     
         6 . The swimming or diving mask according to  claim 1 , wherein the outer frame ( 3 ) covers partially the periphery of the outer surface ( 1 D) of the lenses ( 1 A, 1 B). 
     
     
         7 . A Screwdriver ( 8 ) specially adapted for the assembling or the disassembling of the swimming or diving mask as defined in claims  1  to  7 , said screwdriver being configured to cooperate with the locking/unlocking means ( 6 ) for releasing the outer frame ( 3 ) from the periphery of the outer surface ( 1 D) of the lenses ( 1 A, 1 B), or said screwdriver being adapted for securing the lenses ( 1 A, 1 B) between the outer frame ( 3 ) and the inner frame ( 2 ). 
     
     
         8 . Swimming or diving kit comprising the swimming or diving mask according to  claim 1  and the screwdriver according to  claim 7 . 
     
     
         9 . Method of assembling at least one or two removable lenses ( 1 A, 1 B) in a swimming or diving mask as defined in  claim 1 , comprising the following steps:
 a) placing the periphery of an inner surface ( 1 C) of one or two lenses ( 1 A, 1 B) onto an inner frame ( 2 ) of the mask, said inner frame ( 2 ) having at least one sealing means ( 5 ),   b) placing a removable outer frame ( 3 ) on the periphery of the outer surface ( 1 D) of said lenses ( 1 A, 1 B),   c) locking at least one lock means ( 6 ) located on said removable outer frame ( 3 )   d) clipping at least one clipping means ( 7 ) located on said removable outer frame ( 3 ) and engaging with the inner frame ( 2 ),   e) firmly maintaining said lenses ( 1 A, 1 B) between the inner frame ( 2 ) and the outer frame ( 3 ) with the at least one locking means and/or the at least one clipping means.   
     
     
         10 . Method of disassembling at least one or two removable lenses ( 1 A, 1 B) in a swimming or diving mask as defined in  claim 1 , comprising the following steps:
