The invention relates to an applicator for use on livestock such as cattle, sheep, deer and the like. The applicator include at least two pivotedly connected handle members (2, 3) which extend into upper and lower jaws (4, 5). A driving means (14) com- prising a five sided body portion and elongate tag engagement (16) means to which an ear tag can be attached which are pivotally connected to the upper jaw member (5). There is also provided a biasing means (12) which is in constant contact with one side of the body portion and is used in conjunction with a restraining means (7) to ensure that the tag engagement means (16) is main- tained in a downwardly pointing "cocked" position during application of an ear tag. Upon insertion of the ear tag through the animal's ear, the tag engagement means (16) can be pivoted into a second "spent" position to facilitate easy detachment of the applicator from the ear tag. The orientation of the tag engagement means (16) being determined by the combined effect of the res- training means (7, 11) biasing means (12) and load placed on the tag engagement means (16) itself.
