A device for engaging an elongate article, such as a pipe or cable, for displacing the article longitudinally, comprises a tubular body formed of a plurality of longitudinal parts arranged to be opened apart and then closed together around the elongate article, and at least one collar formed of a plurality of parts carried by respective parts of the tubular body. The collar has a radially inner surface to form an interference engagement with the outer surface of the article, and a radially outer surface to engage the inner surface of the tubular body. The outer surface of the collar and/or the inner surface of the tubular body is tapered towards the trailing end of the device.
