Abstract: An eartag for cattle or other animals comprises an apertured female tab of soft plastics material and a male tab also of soft plastics material having an upstanding stem with a hollow bore, the stem having an enlarged head. A metal pin with a head larger than the head on the stem, the head being formed with a conical point, is inserted in the bore to stiffen the stem and enables the stem to be driven through the animal's ear and secured in the aperture in the female member. The pin is withdrawn leaving an eartag formed wholly of soft plastics material.
