ABSTRACT OF THE DISCLOSURE: An improved sampling device for collecting at least part of air-borne particles in a workman's breathing zone. The device comprises a cassette provided with an inlet, an outlet and an air filter, a vacuum pump and a flexible tubing of determined length connecting the vacuum pump to the outlet of the cassette. In use, a portion of the air contained in the breathing zone of the workman is drawn through the filter and the particles collected thereon. This device is improved in that a deformable metallic tubing is positioned inside a portion of the flexible tubing or is positioned between a short length of a tubing connected to the outlet of the cassette and this flexible tubing. In addition, at least one fastener is provided for fixing the deformable metallic tubing and eventually the flexible tubing, to at least one strap intended to be tightened around a workman's head. This device is useful to position the air-intake of the cassette in the workman's breathing zone.
