The invention relates to a double-jointed bit for horses, the bit comprising two outer lateral parts that are preferably embodied as rings, and a bit part that is arranged between the outer parts and connected thereto. The bit part has two lateral sections and an olive-shaped central section, the central section being connected to each of the two lateral sections by means of an articulated element. The articulated elements are formed by two articulated boreholes embodied in the central section and respectfully a loop provided in each lateral section. The central section comprises a base part and an additional part, the two articulated boreholes being embodied in the base part. The additional part is located essentially between the two articulated boreholes and forms an outer surface of the central section in the region of the central cross-section between the two articulated boreholes.
