A device for gas sampling for gas analysis is provided which uses detector tubes. The device includes a test gas container with a gas inlet pipe, a gas outlet pipe, a mounting opening for the detector tube and with a break-off device for a detector tube tip located in the mounting opening. Nonreturn valves are provided on the gas inlet pipe and the gas outlet pipe. The closing bodies of the nonreturn valves are pressed by springs against corresponding valve seats and are held in a closed position, and are arranged in relation to one another such that a sample gas flow can be established from the gas inlet pipe to the gas outlet pipe.
