Abstract
An elastic connecting piece () is mounted between a carburetor () and an inlet channel () of an internal combustion engine (). The engine () is especially an engine of a portable handheld motor-driven work apparatus such as a motor-driven chain saw, cutoff machine or the like. The connecting piece () includes a peripherally extending expansion fold () arranged between its ends in order to compensate for changes in length. The expansion fold () subdivides the connecting piece () into a carburetor-end section () and into an engine-end section (). The annular gap () of the expansion fold () can be bridged by a seal lip (). The connecting piece () includes a peripherally extending seal seat () of axial length (g) in the region of the expansion fold (). The seal lip () can be placed in seal-tight contact with the seal seat () and substantially closes the expansion fold () fluid tight to the interior space of the connecting piece ().
