There is described the combination of a step for use with a tubular man-hole liner having at least one pair of horizontally located cylindrical holes therein. The step is substantially U-shaped in plan. It has a tread part and a pair of arms extending from the thread part to walls located respectively at the ends of the arms. A pair of cylindrical projections respectively project from the walls to engage in the holes. The outer ends of the projections are hollow and frustoconical plugs are received within the hollow ends and distort them into engagement with the walls.
