In one from DE-PS 21 29 534 known Connection fitting of this type, which is too improve, the mains connection piece ends inside the housing in a valve seat, on which the valve body of the shut-off element is supported under the force of the closing spring.

In that valve, however, it has been shown that the shut-off valve in the event of pressure increases of the inflowing Medium is able to open inadvertently.

The solution to this problem is distinctive λ

for a connection device described above Type in that the shut-off valve is in sight of the flowing through the power line Medium is formed closing.

This has the advantage that the valve body is now pressed onto its seat by the force of the closing spring as well as by the pressure of the medium, so that the valve remains closed in any case, even if the medium pressure is very high, for example when the system is pushed off. There are also significant manufacturing simplifications. It is possible to design the free end face of the power line connection piece as a valve seat.
A preferred, the valve seat during storage and assembly protective development of the above-described object, whereby the functional reliability is further increased, is that the valve seat of the

To further simplify the production of connection fittings of the type described above, the valve body rod being divided into two parts, the first rod part of which is arranged in the housing, tightly closing in the housing partition and is axially adjustable to a limited extent against the force of the valve body closing spring and carries the valve body while the second rod part tightly fits into the housing engages, is rotatably mounted and aligned coaxially with the first rod part and outside of the housing having connection devices for an actuator, and wherein one the Rotary movement of the second rod part in a
