A ball joint is disclosed containing a body of a joint, where there is inserted a pin having a longitudinal axis and including a first threaded end and a second spherical end which is rotatably arranged within a seat of the body and able to co-operate with a first spherical-cap-shaped element or shell inserted within a seat having a corresponding shape of a second spherical-cap-shaped element or shell cooperating with a covering element so as to close the spherical end of the pin within the body. The second spherical end of the pin and the first and second shells including pairs of recesses and ridges in the contact areas are suitable for reciprocally compenetrating, with the pairs of recesses and ridges being arranged at 90° to each other to allow the rotation of the pin along all axes in the space (X, Y, Z). An angular movement sensor integral with the body of the joint is provided, for co-operating with the second element or shell to detect the rotation of the pin around the axis containing the longitudinal axis of the pin.
