Abstract

A handheld work apparatus has at least one tool which is driven by a combustion engine. A portion of an intake channel of the combustion engine is formed by an elastic connecting piece which has a first section and a second section between which an expansion fold is arranged. The expansion fold has a first side wall and a second side wall arranged downstream of the first side wall. A peripheral wall, which extends in the region of the largest outside diameter (a) of the expansion fold, is arranged in flow direction between the first side wall and the second side wall. The connecting piece has a stop for the expansion fold which prevents a segment of the first side wall adjoining the peripheral wall from bearing against the second side wall.
