The invention relates to a fastening device for fastening a toroidal choking coil ( 1 ) to a base or the like, the toroidal choking coil comprising an inner circumference defined by a surface parallel with an axis of rotation of the toroidal choking coil and located closest to the axis of rotation. The toroidal choking coil further comprises an outer circumference defined by a surface parallel with the axis of rotation of the toroidal choking coil and located outermost from the axis of rotation, and side surfaces defined by surfaces perpendicular to the axis of rotation of the toroidal choking coil and connecting the inner circumference and the outer circumference. The fastening device for a toroidal choking coil of the invention comprises at least one pair of choking coil fasteners ( 3 ) consisting of a first choking coil fastener ( 3 a) and a second choking coil fastener ( 3 b), arranged to be installed on opposite side surfaces of the toroidal choking coil ( 1 ), and that at least one choking coil fastener ( 3 a, 3 b) is arranged to come at least partly into contact with the outer circumference of the toroidal choking coil ( 1 ) and at least one choking coil fastener ( 3 a, 3 b) is arranged to come at least partly into contact with the inner circumference of the toroidal choking coil ( 1 ).
