A mounting device includes a first component (10) and a second component (30). The first component has a forwardly disposed nose (15), a rearwardly disposed and outwardly flared cutting member (13), and a bore (11) extending through the nose and cutting member and which is threaded at least along part of its length. The second component (30) comprises a tube (32) for fitting over the nose of the first component. In use, when the tube (32) is fitted over the nose (15) and forced in an axial direction against the cutting member (13) the latter progressively splits the tube substantially parallel to its axis into a plurality of "petals" (40) which become mutually splayed out radially with respect to the axis of the bore (11).
