<p>Apparatus for preventing relative movement between a tube 12 and a collar 114 in a first state of deployment of a deployed refuelling probe, the components being moveable relative to one another in a second state of deployment, the first and second states of deployment being controlled by drive means, the apparatus including a crank assembly 200 also driven by the drive means which moves a locking pin 212 between a first position associated with the first state of deployment and in which the member prevents relative rotation between the two components, and a second position associated with the second state of deployment and in which the locking pin 212 allows relative movement between the two components. <IMAGE></p> |
