Abstract: A receptacle for the connection of gas sensors to a measurng gas chamber has a gas inlet including a feeding line connection for the measuring gas that is equipped with an operable shut-off element. A gas sensor holder is attached and held by a movable compression part that presses it in the direction toward the gas inlet as the gas sensor is attached to the measuring chamber. The feeding line for the measuring gas is connected into a measuring gas chamber and it is opened simultaneously and without additional manipulation and closed again after the removal of the gas sensor from the receptacle. To this end, the compression part is provided with an activating part for the shut-off element of the feeding line.
