A lock plate for preventing relative movement between a first component and an adjoining second component, comprises a first end, a second end, and a planar portion extending between the first end and the second end.The first end is configured to locate against one of the first component and the second component, while the second end is configured to locate against the other one of the first component and the second component.The planar portion comprises a first projection positioned substantially mid-way between the first end and the second end. The first projection protrudes from a plane defined by the planar portion and may readily be severed by a user to thereby separate the first and second component from one another.
