A centraliser for centring one pipe within another comprises a plurality of skids which extend outwards from the outer surface of an inner pipe into contact with the inner surface of an outer pipe The skids are independent of one another and are secured to the outer surface of a pipe with the skids extending radially from the pipe surface. The skids have apertures to receive a securing band or bands which can be passed around the pipe, received in the apertures of the skids and tensioned to secure the skids to the pipe surface.
