Abstract
The identification tag is in the form of a flexible plastic disc having a fastening portion in the shape of an inverted T, the stem of the T extending from a peripheral portion of the disc. A U-shaped strip of metal serves as an inserting tool and is arranged to straddle the disc, a first arm terminating in a square end and the second arm being longer than the first arm and terminating in a point. The arrangement is such that the inverted T-shape can be flexed towards an upright position so that the square end of the first arm can be received between the stem and cross portion of the T with the second arm holding the underside of the second cross portion of the T and stem in their flexed positions. A cow's ear is then pierced by the point on the second arm, the first arm urging the T-shape through the cut opening. Withdrawal of the U-shaped arms then permits the T-shape to flex back to its normal position to secure the tag to the cow's ear.
