A device for elastic ligature of tissues comprises: a first and a second element, one of which exhibits a support portion for at least a rubber ring, the elements being slidably coupled to one another such that a reciprocal sliding between the elements determines a release of a rubber ring from the support portion a trigger, manually maneuverable by an operator and acting on at least the second element for realizing a reciprocal sliding between the elements a connecting portion, connected to the trigger and to the second element and being elastically deformable in order to enable a reciprocal change of orientation between the trigger and the second element.
