Abstract

The invention relates to a portable handheld blower/vacuum apparatus having a housing and a blower scroll formed in the housing. An impeller is provided in the blower scroll. Air is supplied to the blower scroll via an air inlet and air is directed away from the blower scroll via an air outlet. An air-conducting connecting tube is mounted on the air outlet via a housing-fixed connecting stub. A bayonet connection is provided in the overlap region between the connecting tube and the connecting stub. The bayonet connection includes a guide path lying in the overlap region. The guide path includes an axial segment and a peripheral segment connected thereto in which a radial cam of the other part engages. The cam is secured form tight by a latch connection in the peripheral segment of the guide path to ensure a reliable, mechanically loadable attachment of the connecting tube in the connecting stub.
