The disclosure relates to a safety device in an opening arrangement for packaging containers, the opening arrangement having a part fixedly connected to the packaging container and a lid portion displaceable in relation thereto. In the closed position of the opening arrangement, a tongue-shaped projection (9) extends via a slit (15) into a recess (14) in the openable part. The projection (9) will thus be partly visible from the upper side of the opening arrangement until such time as the moving part (4) has been displaced to an open position in which the projection (9) irreversibly departs from the recess (14) and gives a clear, visual indication that the opening arrangement has previously been opened.

[ What is claimed is:] [1.]1. A safety device in an opening arrangement for packaging containers, the opening arrangement comprising two mutually moving parts viz. one part fixedly connected to a packaging container wall and a part movably connected to this fixed part and located on the opposite side of the fixed part in relation to the wall and disposed, in conjunction with the opening of the packaging container, to be displaced between a first, closed position and a second, open position in which a pouring aperture provided in the fixed part is exposed, wherein both parts each include mutually cooperating means which, in the closed position of the opening arrangement, have a first mutual positional relationship and, in the open position of the opening arrangement, have a second, visually different and irreversible positional relationship, said means include, on the one hand, a projection connected to one part and, on the other hand, a recess provided in the other part, the projection in the closed position of the opening arrangement is at least partly located in the recess, wherein the projection is made of a flexible material and is positioned, in the closed position of the opening arrangement, in the recess against a force of flexibility.
