Abstract
A tagging device comprises a strap attached to a housing. A latch plate is mounted on a first length of strap and a collar is slidably mounted on a second length of strap. The latch plate has two location pegs which fit into holes on the first length of strap such that a hole fits over the lug to make the strap the correct size for a user. Two flexible barbs are formed on the collar such that the collar slides over the plate and the barbs are deformed as they slide up slopes on the plate. As the barbs slide off the end of the slopes they return to their rest position and snap into slots. Moving the collar in relation to the plate once the barbs have snapped into place in the slots causes the barbs to break, giving an indication of tampering.
