A vibration isolation device comprises a frame for mounting on an engine casing, an axis to be mounted to an external component to isolate, a resilient member located between the frame and the axis, and a fuse mechanism ensuring that the vibration isolation device presents a first stiffness when loads applied to said vibration isolation device are below a predetermined threshold load, and a second stiffness, lower than the first stiffness, when loads applied to the vibration isolation device are at least equal to the predetermined threshold load. The fuse mechanism constrains the resilient member within a predetermined space when loads applied to the vibration isolation device are below the predetermined threshold load and to release the resilient member so that this latter is capable of deforming beyond said predetermined space when loads applied to the vibration isolation device are at least equal to the predetermined threshold load.
