Disclosed is a force applying device for orthodontic treatment being elastically expandable and configured to generate a restoring force as an orthodontic force for an orthodontic treatment when compressed. The force applying device comprises a first element and a second element capable of moving relative to each other along a first axis. The force applying device for orthodontic treatment is compressed when the first and second elements move towards each other along the first axis. A first arm extends laterally from a first end of the first element away from the second element. A first connecting part of a first connector is fitted over the first arm. A second connecting part of the first connector is to be fitted over a button fixed on a first jaw to connect the first element to the first jaw. Both the first and the second connecting parts are toroidal in shape.
