A surface access assembly 10 includes a first cover 12a and a second cover 12B. Each of the covers 12A, 12B include a substantially planar surface part 20. The assembly 10 includes an interlocking member 54, which in an interlocked condition extends between the first cover 12A and the second cover 12B to secure the first and second covers 12A, 12B together. The assembly 10 is arranged so that the interlocking member 54 extends in a direction substantially normal to the plane of the surface parts 20. |
