The invention concerns a method for mounting a sprung joint for the frame of spectacles, comprising a step which consists in placing a spring pin in a first component and a step which consists in articulating the first component to a second component through a pivot pin enabling a bow of the frame, integral with one of the components, to pivot relative to a surface of the frame integral with the other component. The invention is characterised in that it consists in: opening the first component by elastic deformation, inserting the spring pin into the first component, and closing the later around the pin so as to retain it by elastic pinching against the spring compression. Preferably, the first component is forcefully opened with the pin. The method enables to simplify mounting a spring joint wherein the pin is permanently retained in the first component even if the pivot pin is lost.
