Abstract
A device for adjusting the stiffness of a suspension spring includes a locking sleeve which defines a helical slot for accepting one end of the suspension spring, and an adjusting ring mounted with the ability to rotate relative to the locking sleeve about a main axis. The adjusting ring has a finger which emerges into the helical slot and is able to form an end stop for the end of the suspension spring. Structure is provided for locking the rotational mobility of the adjusting ring relative to the locking sleeve.
