         2 . Device ( 1 ) according to the  claim 1 , wherein said second element ( 6 ) comprises a ring-nut body ( 8 ). 
     
     
         3 . Device ( 1 ) according to the  claim 2 , wherein said screw connection means ( 7 ) comprise at least a substantially helical ramp ( 9 ) associated with said ring-nut body ( 8 ) and a fastening body ( 10 ) associated with said gripping body ( 4 ) and suited to engage said ramp ( 9 ) during the screwing of said second element ( 6 ) on said first element ( 2 ). 
     
     
         4 . Device ( 1 ) according to the  claim 3 , wherein said ramp ( 9 ) is arranged inside said ring-nut body ( 8 ), which can be fitted around said gripping body ( 4 ). 
     
     
         5 . Device ( 1 ) according to the  claim 3 , wherein said ramp ( 9 ) comprises a side notch ( 14 ) which can be engaged by a locking blade ( 15 ) associated with said gripping body ( 4 ). 
     
     
         6 . Device ( 1 ) according to the  claim 3 , wherein said fastening body ( 10 ) comprises a first inclined edge ( 11 ) having substantially the same inclination as said ramp ( 9 ). 
     
     
         7 . Device ( 1 ) according to the  claim 6 , wherein said fastening body ( 10 ) comprises a second inclined edge ( 12 ) that, with respect to the lying plane of said gripping body ( 4 ), is substantially symmetrical to said first inclined edge ( 11 ). 
     
     
         8 . Device ( 1 ) according to the  claim 6 , wherein said screw connection means ( 7 ) comprise two of said ramps ( 9 ) arranged on diametrically opposite sides of said ring-nut body ( 8 ) and two of said fastening bodies ( 10 ) arranged on substantially opposite sides of said gripping body ( 4 ). 
     
     
         9 . Device ( 1 ) according to the  claim 8 , wherein the projections of said ramps ( 9 ) on a plane at right angles to said rotation axis (R) are substantially at a distance to define two corresponding fitting seats ( 13 ) for fitting said fastening bodies ( 10 ). 
     
     
         10 . Device ( 1 ) according to the  claim 2 , wherein said ring-nut body ( 8 ) comprises a padded annular surface ( 16 ) suited to come into contact with said plate-shaped products (M). 
     
     
         11 . Device ( 1 ) according to the  claim 2 , wherein that said ring-nut body ( 8 ) comprises at least an external ribbing ( 17 ,  17   a ) which extends laterally and is suited to make the gripping easier by a user. 
     
     
         12 . Device ( 1 ) according to the  claim 9 , wherein said ring-nut body ( 8 ) comprises a plurality of external ribbings ( 17 ,  17   a ) which extend laterally and are suited to make the gripping easier by a user and wherein at least one ( 17   a ) of said external ribbings is placed in correspondence to one of said fitting seats ( 13 ) and has a different thickness than the other external ribbings. 
     
     
         13 . Device ( 1 ) according to the  claim 1 , wherein said gripping body ( 4 ) comprises at least a grip ( 5 ) suited to allow the gripping by a user. 
     
     
         14 . Device ( 1 ) according to the  claim 1 , wherein said first element ( 2 ) is made of a breakable material suited to allow the removal by breaking of said gripping body ( 4 ) once the installation of said plate-shaped products (M) has been completed. 
     
     
         15 . Device ( 1 ) according to the  claim 14 , wherein said first element ( 2 ) comprises at least a weakened section ( 18 ) suited to favour said removal by fracture of the gripping body ( 4 ).
