A tag for application to the ear of an animal includes a male portion (2) and female portion (3). The female portion includes a chamber (13) within which an insert (14) is accommodated, the insert engaging in an interlocking manner with the chamber and allowing access of a head (9) of the male portion into the chamber but then acting to prevent removal of the head. The male and female portions may be connected at a central portion (4) which enables folding of the male and female portions. In another embodiment, the central portion may include a weak-link so that the male and female portions can be torn apart if the tag becomes caught on an obstruction.
