Abstract: An applicator of the present invention generally comprises too pivotally connected handle members, extending into upper and lower jaws. The lower jaw includes a lip, the lower jaw and lip defining a space into which an animals ear is located. The lower jaw further includes a recess, with a pivotal bar extending thereacross. In use, an eartag is positioned on a pivotally mounted pin. The handles are brought together, bringing the pin and tag passed the lip portion, through the ear of the animal (forming a cut therein) and through the recess described above. The pivotal bar stops or at least reduces movement of the ear into the recess, which has previously resulted in too large a cut being formed in the ear, and which has made the tag more difficult to apply.
