ABSTRACT:
In a fastening device for the dust-tight fastening of filter bags in a separation plate between crude gas and purified gas chambers in dust-laden gas filters, an elastic nipple, formed as a slit ring, is inserted into the open end of each filter bag.
In order to produce the radially acting fastening and sealing force, a clamping ring (6) is swingably supported in the nipple (5), said ring being provided with flats (6a) on two sides which are opposite each other. On each side of the slit in the nipple (5) two protrusions (5b) are provided between which the clamping ring (6) is locked in installed condition. In unlocked upward swung condition upon the installing or removal of the nipple (5), the clamping ring (6) can be used as handle, either without or with attached filter supporting basket (5c).
