The second portion is co-operable with the first portion and adapted to fit around the rest of the neck adjoining the flange such that together the first and second portions can encircle the neck of the article. At least one detent is provided which is connected to one of the portions and which can engage a part of the other portion to lock the two portions together. A tell-tale security provision is enclosed within a receptacle defined by at least one of the first and the second portions.
