The present invention relates to a device for restraining an energy store (100) comprising one or more cells disposed between a first side of the energy store and a second side of the energy store vertically opposite to the first side. The device comprises at least one first mounting device (202) designed for transferring a first clamping force acting in the direction of the second side to the first side of the energy store, and at least one second mounting device designed for transferring a second clamping force acting in the direction of the first side to the second side of the energy store, and at least one elastic clamping device (206) designed for providing the first and second clamping forces and further designed for adapting a distance between the at least one first mounting device and the at least one second mounting device to a permissible distance between the first and the second side.
