A locking arrangement for an electrical switchboard cabinet (1) comprising: - a frame (10) delimiting an internal space (11) of the cabinet (1); - a door (100) operatively connected to said frame (10), said door (100) having a first surface (101) facing said internal space (11) when the door (100) is in a closed position, and a second surface (102) opposed to said first surface (101) and facing the external of the cabinet (1); - a locking element (30) connected to the frame (10); - a mechanism (200) which is adapted to be actuated for operatively interacting with said at least one locking element (30) and locking the door (100) in the closed position; and -that the one locking element (30) is adapted to pass through the door (100) in the closed position by means of a corresponding opening (40) extending between the first surface (101) and the second surface (102), and that mechanism (200) is operatively coupled to said second surface (102) for operatively interacting with the locking element (30) when the door (100) is in the closed position.
