A spring brake actuator having a flange case and a head is provided. The flange case includes a radially outwardly extending annular flange, and the head includes a shoulder and a collar extending therefrom. The collar includes a plurality of radially spaced apart slots defining a plurality of radially spaced apart tabs, each of the tabs having a hook portion projecting radially inwardly, and each of the tabs being elastically deformable radially outwardly. In an assembled position, when the head is attached to the flange case, the annular flange of the flange case is received by the collar of the head and the hook portions of the tabs engage a lower surface of the annular flange so as to inhibit separation of the head from the flange case. A method of assembling such a spring bake actuator is also provided
