摘要

The present invention relates to a spacer (50) for securing an inner tube (51) in an outer tube (52). The spacer comprises: an enclosing part for enclosing the inner tube all round as well as at least two radial projections (7-10,24,25) provided on the enclosing part for engaging on the inside of the outer tube. The radial projections, viewed in the axial direction, have a surface (30) converging towards the inner tube. This converging surface in particular tapers. The spacer can be produced from a single sheet section by means of punching and setting operations. The invention furthermore relates to an assembly of a spacer with an inner tube and/or outer tube.
