Summary:The invention concerns an open-loop current sensor (1) comprising a mount casing (2) in which a magnetic circuit (3) is arranged comprising a magnetic core (5) and a measuring air gap (8), a magnetic field detector (4) being positioned in the measuring air gap (8) to measure the magnetic field induced by the electric current circulating in a cable passing through the magnetic circuit (3). The sensor (1) also comprises connection systems (18) between the casing (2) and the terminal parts (6) of the magnetic circuit (3) to maintain a constant width of the measuring air gap.
