       2 . The arrangement as set forth in  claim 1 , characterized in that the tubular projections ( 31 ) have their longitudinal extension dimensioned to maintain the tray ( 30 ) spaced from the upper wall ( 10 ) of the cabinet (G).  
   
   
       3 . The arrangement as set forth in  claim 1 , characterized in that each tubular projection ( 31 ) incorporates an internal transversal wall ( 32 ) which is lowered in relation to the tray ( 30 ) and provided with a through hole ( 32   a ) for mounting the respective screw ( 40 ).  
   
   
       4 . The arrangement as set forth in  claim 1 , characterized in that the tubular projections ( 31 ) are incorporated in a single piece to the tray ( 30 ).  
   
   
       5 . The arrangement as set forth in  claim 4 , characterized in that the tray ( 30 ) comprises a basic plate ( 33 ) provided with a through opening ( 34 ), coaxial to a respective tubular projection ( 31 ) and which is formed in the bottom of a respective lower recess ( 35 ) of the basic plate ( 33 ).  
   
   
       6 . The arrangement as set forth in  claim 5 , characterized in that each upper recess ( 35 ) of the basic plate ( 33 ) is provided with at least one radial slot ( 36 ), opened to the interior of the through opening ( 34 ) and inside which is seated and retained, by fitting, a salience ( 51 ) which is inferiorly incorporated to a cover disc ( 50 ) to be fitted inside the upper recess ( 35 ).  
   
   
       7 . The arrangement as set forth in  claim 5 , characterized in that the basic plate ( 30 ) incorporates, in a single piece, a peripheral rib ( 37 ) in high relief and downwardly extending in the form of a peripheral lower skirt ( 38 ).  
   
   
       8 . The arrangement as set forth in  claim 1 , characterized in that each hole ( 12 ) of the upper wall ( 10 ) of the cabinet (G) is defined in an annular bottom wall of a recess ( 11 ) of said upper wall ( 10 ), which is dimensioned to receive and fit, with a small gap, the lower end of a respective tubular projection ( 31 ).  
   
   
       9 . The arrangement as set forth in  claim 1 , characterized in that the tubular retaining means ( 20 ) is defined by a nut which is inserted and retained inside the hole ( 12 ) of the upper wall ( 10 ).
