Abstract: A transport arrangement having an inner container, preferably having at least one apron projecting beyond an end face of the inner container, an outer container, which receives the inner container, and a twist prevention device, by means of which the containers can be locked together to prevent them from twisting about their longitudinal axes. The twist prevention device has a locking element that is axially adjustable in a first receptacle, a second receptacle that rotatably receives the first receptacle and is fixedly connected to one of the containers, and a handle that extends from the first receptacle and is radially guided by the second receptacle, the pivoting movement of said handle being convertible via the first receptacle into the axial adjustment of the locking element for engagement in the other container or disengagement therefrom.

Abstract: A closure device for containers for transporting radioactive substances, having a first and a second component each with a comb-like portion, wherein the comb-like portions, with the closure device locked, has a bolt element passing through them. The bolt element has a head with an accommodating recess running transversally to the longitudinal axis of the bolt element, that one of the components has a through-opening which, with the bolt passing through the comb-like portions, is aligned with an accommodating recess.
