The mouth-piece comprises a tubular body which accommodates a filter element which defines, with the inner walls of the tubular body, a first collection chamber for the combustion products, while a second collection chamber for the condensation products is defined in the same tubular body by a slot which extends into the tubular body and is rigidly connected thereto. The filter element has a nucleus of truncated cone shape, which is completely inserted inside the tubular body and has a face in abutment with the end of a cigarette.
