Linking system of two or more cinematographic projection machines to synchronize their respective gears, consisting essentially of the fact that they connect their main axes, receiving movement from the corresponding motors, transmitting them to the projector's mechanisms, either the axes of the aforementioned motors by means of a solid or tubular rigid rod of suitable length which, being removable, is provided at each end with corresponding corresponding ball-and-socket joints, each of these having at its end a profile which is insertable with that provided for this purpose at the end of the axis that adapts being longitudinally displaceable one of said appendices acting as a trigger that by the action of a spring is maintained with permanent tendency to establish connection with the axis on its side giving the characteristic circumstance to link the main axes of the projectors dispose perforated the ca squillo-cojinete that holds its internal end and the wall of the projector at the point that it is properly applied so that prolonged or not the aforementioned axis can establish the coupling by fitting or plug its end with the appendix on its side of the connection bar.
