ABSTRACT:
A grip unit for a suction hose of a vacuum cleaner system defines both air and electrical connections to further components of the system such as a suction pipe, nozzle and the like. The grip unit includes a one-piece insert member which is preassembled and then inserted into a tubular member. The one-piece insert member accommodates all electrical components or accessories and, in the inserted position, this insert member defines a sealed air guide and a channel for the electrical parts. The simplified configuration substantially simplifies assembly and reduces the cost to manufacture the unit.
