System linker for applying a ligating ring expanded by an anatomical area of a living being to be ligated by the ring in its relaxed state, comprising a linker (1) with a tube (2) retention and a tube (3 ) feed, wherein the tube (2) retaining stays within the anatomical region to be ligated in each case with its outer surface can keep tensioned several ligating rings arranged one behind the other, the system comprising linker addition at least two ligating rings, characterized in that the system linker further comprises at least one intermediate ring (12) consists of a material different from that of the ligating rings, which is arranged on the tube (2) retaining between two ligating rings and maintains both ligating rings spaced apart in the longitudinal axis direction (L) of the tube (2) retaining both ligating rings and the intermediate ring being arranged to be among them on the holding tube Linker (1) so that to trigger one of the ligating rings in question via the tube (3) forward these can be pushed together along the holding tube towards its end distal.Sistema de ligador para aplicar un anillo de ligadura expandido en una zona anatómica de un ser vivo que va a ligarse por el anillo en su estado relajado, que comprende un ligador (1) con un tubo (2) de retención y un tubo (3) de avance, en el que el tubo (2) de retención puede alojar en su interior la zona anatómica que va a ligarse en cada caso y con su superficie exterior puede mantener tensados varios anillos de ligadura dispuestos uno detrás de otro, comprendiendo el sistema de ligador adicionalmente al menos dos anillos de ligadura, caracterizado porque el sistema de ligador comprende además al menos un anillo (12) intermedio compuesto por un material distinto del de los anillos de ligadura, que está dispuesto sobre el tubo (2) de retención entre dos anillos de ligadura y mantiene ambos anillos de ligadura distanciados entre sí en la dirección del eje (L) longitudinal del tubo (2) de retención, estando
