SENSOR FOR MEASURING A CURRENT IN AN ELECTRIC CABLE Sensor (1) for measuring a current in an electric cable, comprising an electrical circuit (4) and a support (6) for the electrical circuit, with the electrical circuit being intended to surround the electric cable during said measurement by forming a loop, the support having an opening (12) and comprising two ends (14, 5 16) located on either side of the opening, the electrical circuit comprising a helical winding. The support is elastically deformable between a first position wherein it is at rest and the two ends are substantially face-to-face, and a second position wherein the two ends are separated from each other in relation to the first position, 10 with the support being sufficiently flexible and being formed in such a way that: - the support can be deformed from the first position towards the second position by pressing manually the opening of the support against the electric cable, in such a way as to pass the electric cable from the outside of the loop towards the inside of the loop, or from the inside of the loop towards the outside of the loop, 15 and - the support spontaneously passes back from the second position to the first position, once the electric cable has passed through the opening.
