Abstract
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 (,) extends via a slit (,) into a recess (,) in the openable part. The projection (,) will thus be partly visible from the upper side of the opening arrangement until such time as the moving part (,) has been displaced to an open position in which the projection (,) irreversibly departs from the recess (,) and gives a clear, visual indication that the opening arrangement has previously been opened.
