ABSTRACT OF THE DISCLOSURE A protective casing for preventing any accidental introduction of metal parts into a column containing an array of electric distribution busbars is made up of two identical insulating half-casings (3) coupled together by interengagement of external engagement regions (18A, 20A, 22A, 24A) and of internal engagement regions (18B, 20B, 22B, 24B) up to a mutual coupling position which is variable according to the dimension of the busbars. The busbars are inserted in housings (29, 30) and pass through recesses (9A, 11A, 11B, 9B, 13) in the lateral walls of the casing. Fixing bolts extending between the busbars are surrounded by insulating sleeves (21) formed by interpenetrating outer and inner tongues (23 and 25) separated by slits (36). The sleeves (21) are made integral with the half-casings by molding of plastic material.
