The invention relates to a suction hose connecting piece (10) for a suction hose (100) for producing a flow connection, particularly from a machine tool to a vacuum cleaner, said connecting piece (10) having a tubular body (11) with a circumferential wall that delimits a flow channel, and a plug section (50) that is arranged on said tubular body (11) for the purpose of producing a plug connection with a mating connecting piece, it being possible to plug said connecting piece (10) and mating connecting piece one onto the other, and said plug section (50) consisting of a material that is elastically more yielding than the tubular body (11). According to the invention, at least one rotational form-fit contour (70) is arranged on the plug section (50) in order to produce a form-fit connection with a rotational form-fit mating contour of said mating connecting piece, at least one rotational form-fit contour (70) being able to be brought into or out of engagement with said rotational form-fit mating contour by means of a relative rotational movement of said connecting piece (10) and mating connecting piece, about a longitudinal axis (L) of the plug section (50). |
