A magazine for mounting twist locks includes a rotatably mounted drum having a plurality of axially oriented elongated guide elements, which are arranged at a distance from each other on the circumference of the drum and the longitudinal axes of which are oriented parallel to each other. The distance between the guide elements is larger than the diameter of a concave section of a respective twist lock and the guide elements form the support for the terminal sections of the twist lock. Closing elements are arranged at each end of the drum and delimit the intermediate spaces formed by the guide elements in the radial direction. One closing element is arranged in a non-rotatable manner and has a radially oriented recess for inserting twist locks between two guide elements in the axial direction.
