A locking device (36) for use in retaining an assembly of rotor blades against movement around a rotor disc on which they are mounted comprises a body member having first and second portions interconnected by a weakened region (66) whereby a force applied to turn the first portion (38) relative to the second portion (40) can cause them to shear apart at said weakened region (66) thereby facilitating release of seized devices to enable blade removal.
