A steering column assembly comprises a shroud having an upper shroud part and a lower shroud part movable telescopically relative to one another, and a steering shaft. The upper shroud part carries an energy absorbing device which in normal use moves together with the upper shroud part. A blocking device is fixed to the lower shroud part or to a part of the vehicle that is fixed relative to the lower shroud part; and a connecting rod is connected at a first end to the blocking device and at a second end to a spring which is in turn connected to the lower shroud part or to the fixed part of the vehicle. An initiator module engages with a part of the connecting rod or spring when the blocking mechanism is in the unlocked position thereby to isolate the blocking device from the force of the spring.
