An electrically heated composite glass panel designed to form walls for shower stalls, comprising: a first glass sheet, a second glass sheet having the same outline as the first glass sheet and superimposed thereon, an intermediate layer of electrically non-conducting material disposed between the first and the second glass sheet, the intermediate layer being designed to form a composite structure with the glass sheets, a layer of electrically conducting material positioned and extending between the intermediate layer and a surface of said first glass sheet facing the intermediate layer, said layer of electrically conducting material extending so as to form a border zone (13,14,19,20) of the surface of said first glass sheet, the border zone being free from electrically conducting material, wherein said layer of electrically conducting material is spaced from the outline border (9, 10, 15, 16) of the first glass sheet and of the intermediate layer characterised in that said layer of electrically conducting material forms two zones (6, 7) separated from one another by a non-electrically conducting section of the surface free from the layer of electrically conducting material, each zone (6, 7) is provided with a first and a second electrical terminal (21, 22), in the form of electrodes, being connected to and in contact with the layer of electrically conducting material at points spaced from one another, both electrical terminals (21, 22) being accessible from outside the first glass sheet by causing them to pass through a respective hole (23, 23a), the two zones (6,7) are spaced from the outline border (9, 10, 15, 16) of the first glass sheet and are connected to the respective terminal (21, 22), the first and second electrical terminals being positioned at the location of a first section of the outline of the first glass sheet, each zone being electrically connected to the other at the location of a second section of the outline of the first glass sheet, said second section of the outline being opposite to the first section of the outline and spaced therefrom, the first and second electrical terminals (21, 22) comprise a respective section (21 a, 22a) housed in respective recesses (29, 30) of a plate secured to the outer surface of the first glass sheet, the section of terminal being spaced from an inner wall (29a, 30a) of the relative recess (29, 30) through the formation of a surrounding annular space, and a box-shaped member secured to the plate rigid with the first glass sheet, the box-shaped member containing electricity supply terminals which can be coupled to the sections (21 a, 22a) of the first and second electrical terminals (21, 22) housed in said respective recesses (29, 30). a first
