Abstract The invention relates to an expanding means for removable fastening in a cylindric hole, consisting of an elastic cyl- inder, which is caused by axial contraction to expand and with the outer surface to engage with the cylindric hole, which cylinder is formed with a plurality of bars, which extend substantially in the axial direction of the cylinder. It is a known problem that, when the expanding means is located within a hole in the form of a cylinder, problems may arise in carrying out the expanding proper of the expanding means, because it is difficult for the operator to control by a tool or the like the expanding proper of the expanding means. This problem is overcome in that the bars (7) extend from grooves (8) running in the direction of the bars in the outer surface of the cylinder (1) and outward outside the outer surface.
