Abstract
Description
technical field
[0001] The present invention relates to a connection device which ensures the connection of flexible ventilation ducts to main ventilation ducts, distribution points and various fans, devices and ventilation equipment and which, unlike existing connection devices, is threaded to The flexible ventilation duct is mounted on and thus the flexible ventilation duct acts as a natural gasket by being extruded and the connection means allows a more leak-proof, stronger, more practical, more economical and more flexible connection. Background technique
[0002] In the prior art it is common to use plastic clips and insulating tapes when connecting flexible ventilation ducts to main ducts, certain distribution points, various fans, fixtures and ventilation equipment. On the part of the flexible ventilation duct that will be connected to the main ventilation duct there is a metal end fixed and a plastic clip fits over the joint. After surrounding the joint area with a ...
