A DUST SEPARATION BAG CONNECTION DEVICE AND BAG THEREFOR

摘要

A dustbag (4) is, at the neck end thereof, provided with a concentric elastomer ring (50) that in the unloaded state has a substantially smaller circumference than the free diameter of the bag neck (48). A vacuum-cleaner socket (1) has a conical threading end (12) having a waist following thereon that receives the ring (50) of the bag. The socket carries a clamping ring (20) and a tightening device (70) for pressing of the clamping ring (20) against the bag-neck ring (50). The bag as well as the device for attaching the same are made use of.
