3) is aeuea design features are based on the Fig. In and 2 are described as design features.

Both i * ig "are sectional drawings" Fig. 1 shows the firing position in the relaxed, empty state ₉ J ¹ Ig ₀ 2 on the other hand not inserted and mechanically firmly gripped the Biahtungsbuöhse 7 gas-tight with the collet 4

The hollow clamping head 1 acts by means of an internal winch on the Pressure body 3 a of the device. The is located between the clamping head 1 and the pressure body 3a of the device Ball bearing 6, through which the friction between the clamping head 1 and pressure body 3 a is practically eliminated and only the Force is to be overcome, which the pressure body 3a # «« i on the Collet 4 exerts when pressed together.

While with known pipe holders the pressure hull ?! with the Protective cover forms a unitary body 3, the protective cover 3 b is now a body of its own, the front one Forehead and the larger part of the diehtunga bushing 7 encloses. When the collet 4 is pressed together this is pressed into the body 2 in the axial direction as a result of the screwing movement of the clamping head 1. Here presses the over the front forehead of the protective cover 3b Dichtuiagsbuchse 7 together. In Fig. 2 it is shown how it fills the free space 11 in FIG. 1 in the open state and presses itself tightly around the combustion tube 14.

So that the combustion tube 14 can follow the movement of the collet 3 a, according to the invention there is a stop end for the combustion tube 14 designed elastically yielding. The combustion tube hits an inner edge in the further, stepped sleeve 9 " The rear thinner part of this sleeve is surrounded by a rubber bushing or compression spring 1o. This is based on the base of the body 2 and can when pressed together inwards into the space 12 and outwards into the recess evade.

As a result, the combustion tube 14 moves along with the displacement allows the collet 4, while it is always firmly on the elastisoh yielding floor or stop is seated in the protective sleeve 9. Additional frictional forces in the sealing bush 7 are largely avoided and the same as the mechanically firm grip of the Burning tube 14 through the collet 4 a secure seal Outcome achieved.
