Regulating means designed to regulate a position between: - a base part of a vehicle steering wheel such as a frame, and - an added piece of the vehicle steering wheel, comprising, for example, a security module, and placed on the base part, by at least one centring portion integral with the base part or with the added piece, which regulating means is designed to engage with the base part or with the added piece, and comprising a reference surface designed to engage with said at least one centring portion, which regulating means comprises at least one regulating module with: - at least one receiving element extending along a projection direction, - at least one regulating element (32; 32a) with a counter-shape designed to receive the at least one receiving element in order to prevent a rotation about the projection direction between said at least one receiving element and said at least one regulating element (32; 32a), and in which said at least one regulating element (32; 32a) is designed to be assembled with said at least one receiving element according to a first mounting position or to at least a second mounting position, and characterized in that one of said at least one receiving element or said at least one regulating element (32; 32a) is integral with the reference surface and offset relative to the reference surface in order to offset the other one of said at least one receiving element or said at least one regulating element (32; 32a) relative to the centring portion when the reference surface is engaged with the centring portion in such a manner as to impose a first position of the added piece relative to the base part in the first mounting position, or to impose a second position of the added piece relative to the base part in the second mounting position. - a base part of a vehicle steering wheel such as a frame, and - an added piece of the vehicle steering wheel, comprising, for example, a security module, and placed on the base part, by at least one centring portion integral with the base part or with the added piece, which regulating means is designed to engage with the base part or with the added piece, and comprising a reference surface designed to engage with said at least one centring portion, which regulating means comprises at least one regulating module with: - at least one receiving element extending along a projection direction, - at least one regulating element (32; 32a) with a counter-shape designed to receive the at least one receiving element in order to prevent a rotation about the projection direction between said at least one receiving element and said at least one regulating element (32; 32a), and in which said at least one regulating element (32; 32a) is designed to be assembled with said at least one receiving element according to a first mounting position or to at least a second mounting position, and characterized in that one of said at least one receiving element or said at least one regulating element (32; 32a) is integral with the reference surface and offset relative to the reference surface in order to offset the other one of said at least one receiving element or said at least one regulating element (32; 32a) relative to the centring portion when the reference surface is engaged with the centring portion in such a manner as to impose a first position of the added piece relative to the base part in the first mounting position, or to impose a second position of the added piece relative to the base part in the second mounting position. - at least one receiving element extending along a projection direction, - at least one regulating element (32; 32a) with a counter-shape designed to receive the at least one receiving element in order to prevent a rotation about the projection direction between said at least one receiving element and said at least one regulating element (32; 32a),
