Abstract An animal ear tag application having two lever members pivoted together, one side of the levers at their pivot formed as handles and the other side formed as jaws, a pin fixed to the jaw of a first one of the lever members directed towards the jaw of a second one of the lever members and having an ear-piercing free end, the jaw of the second lever member formed with an open slot from its side facing the jaw of the first lever member and a hole passing through the jaw behind the open slot, an open-slotted plate centrally pivoted to the jaw of the second lever member and spring-loaded thereto, the slots being in line, and a spring arranged between the levers at their handle side of the pivot to normally move the jaws away from each other, the construction and arrangement being such that with a headed tubular male component of an ear tag mounted on the fixed pin of the jaw of the first lever member beyond the ear-piercing free end of the pin and a female component of the ear tag being located in the open slot of the jaw of the second lever member behind the plate of such jaw retained by the spring-loaded plate; on a closing of the jaws towards an animal''s ear located between the jaws, the free end of the pin will pierce the animal''s ear, then carrying the tubular male component through the female component and be secured thereby; upon release of handle pressure, the jaws will be opened by spring pressure and the pin withdrawn from the tag and the animal''s ear.
