A hinge for coupling a body and a button cover of a radiotelephone has a can, a first member, a second member and a spring. The can has an partially closed end and an open end. A retaining protrusions are provided to close the open end by way of bending. The first member has a shaft protruding through the partially closed end of the can and two protrusions defining a cam follower. The second member has a cam portion interacting with the cam follower. The cam portion includes at least a peak and two valleys separated by the peak and slopes connecting the peak and the valleys. The spring pushes the second member toward the first member. The first member, the second member and the spring are contained within the can in turn. Then, the protrusions are bended.
