ABSTRACT:
A device for detachably securing a dust filter bag in dust aspirating equipment, comprises a flange part of rigid material seated externally on the bag wall and having a passage opening aligned with an inlet opening in the bag wall, and an equipment specific adapter plate of rigid material, which on the one hand is able to be secured to the dust aspirating equipment and on the other hand is able to be detachably connected with the flange part by means of a plug and detent joint. The adapter plate has a through opening which in the connected state is flush with the passage opening in the flange part and together with same has a through opening constituting a flow opening with the same and an annular seal and in the connected state effective between the adapter plate and the flange part for sealing off the through opening from the outside. The flange part in a oblique position inclined away from the adapter plate, is able to be plugged to the adapter plate and in the plugged state is connected with the adapter plate so that the flange part is able to be pivoted toward the adapter plate into a position of use connected by detent means with the adapter plate and arranged coaxially in relation to the adapter plate, in which position a sealing face on the flange part or of the adapter plate is held against the annular seal arranged on the adapter plate or, respectively, the flange part.
