Abstract
Abstract In a device to secure the shoulder straps of a backpack or rucksack, fittings are fitted to the upper ends of the shoulder straps and are pivotally mounted together on a retaining piece. In the preferred embodiment the fittings are situated in the middle of the rucksack and the pivotal mounting of one or both shoulder straps is constructed so as to be continuously adjustable in various angles at the retaining piece. The arrangement permits adjustment of the lateral distance between the shoulder straps in the shoulder region both simply and rapidly to suit the build of the wearer, so that the shoulder straps are always supported in the optimum position.
