A magnetic current sensor, comprising: - a magnetic circuit which is designed to surround an electrical conductor forming a primary circuit for the magnetic circuit, - an electrical winding, which includes two ends (520, 521), as well as a running part which connects the two ends and which is wound around a portion of the magnetic circuit, - an insulating coil, which defines a coil axis on which the coil is substantially centred, and which includes two end parts (530, 531) which are opposite each other along the coil axis, the coil being radially interposed between said portion of the magnetic circuit, which is received within the coil, and the winding, which is coaxially wound on the coil, the magnetic current sensor is characterised in that it comprises - two connection pins (54, 55), which are respectively mounted on the end parts (530, 531) of the coil and which are respectively connected to the ends (520, 521) of the winding, wherein each connection pin (54, 55) includes a main body (540, 550) which is: - received in a complementary manner in a housing (533, 534) provided in the corresponding end part (530, 531) of the coil, - elongated along a body axis extending transversely to the coil axis, and - provided with a first side face, which faces towards the coil axis, and a second side face, which faces away from the coil axis, and wherein each connection pin (54, 55) also includes two tabs (541, 542, 551, 552) which: - project from the first side face of the main body (540, 550), each running from an end (541.1, 542.1) where it joins the main body to a free end (541.2, 542.2), - are spaced apart along the body axis, - at their junction end with the main body, extend from the first side face of the main body along respective tab axes (X541, X542), which are parallel and each extend transversely to the coil axis and the body axis, and - between their junction end with the main body and their free end, are folded against the same side wall (533.1) of the corresponding housing (533, 534) so as to hold the connection pin in position relative to the coil. -
