A lockable telescopic actuator arranged to be in a locked state or in an unlocked state, the lockable telescopic actuator including: a body defining a cylindrical cavity; a piston mounted to slide in the cylindrical cavity; and a locking mechanism including a first locking segment, arranged to move from a locked position to an unlocked position. In the locked position the first locking segment is engaged with the piston to prevent the piston from moving. In the unlocked position the first locking segment is disengaged from the piston to allow the piston to move. A first shape memory alloy, SMA, biasing element configured to be extended or compressed such that when the first SMA biasing element is compressed the first locking element is biased into the locked position and when the first SMA bias element is extended the first locking element is biased into the unlocked position.
