ABSTRACT:
A gas cylinder with an outer steel tube which has its lower end of a smaller diameter. Into the upper end of the tube a plastic bushing provided with longitudinal radial ribs is inserted under pressure. This bushing has two annular reinforcing portions separated a certain distance from each other, with the ribs being situated further back in this separation, so that staggered housings are produced all around the profile, in which hook-type fins are received, with semi-punched material on the wall of the tube. At the lower end, an inverted bowl is placed, with its edge supported on a flange on the end of the tube.
