Practical flexible connecting apparatus for ventilation duct

Abstract

The invention is about a connecting apparatus which ensures the connection of the flexible ventilation ducts to the main ventilation ducts, distribution points and all kinds of fan, device and ventilation equipment, and which, distinctly from the existing connecting apparatuses, is installed by being screwed onto the flexible ventilation duct and thereby where the flexible ventilation duct serves as a natural gasket by being squeezed, and which allows for a more leak-proof, more resistant, snore practical, more economic and more flexible connection.

1 . The invention is a connecting apparatus ( 1 ) which practically fixes the flexible ventilation ducts ( 2 ) to a main ventilation area or to a connection point without any need for a plastic clamp or tapes, and its feature is that it is characterized by the fact that the said flexible ventilation duct ( 2 ) contains one fastening ring ( 5 ) by which it fastens tightly by encircling from an end, and at least one mounting protrusion ( 3 ) located towards the exterior of the said fastening ring perpendicular to the center of the said duct, and at least one mounting hole ( 4 ) for fixing the said flexible ventilation duct ( 2 ) fastened by the said mounting protrusion ( 3 ) to a main duct with a connection means such as a screw. 
     
     
         2 . It is a connecting apparatus ( 1 ) according to the  claim 1 , and its feature is that; it is characterized by the fact that the said apparatus serves as a natural gasket between the said apparatus ( 1 ) and said flexible ventilation duct ( 2 ) and the main duct or the connection point which it is intended to be penetrated through. 
     
     
         3 . The invention is a connecting apparatus ( 1 ) which practically fixes the flexible ventilation ducts ( 2 ) to a main ventilation area or to a connection point without any need for a plastic clamp or tapes, and its feature is that it is characterized by the fact that the said ventilation duct ( 2 ) has at least one mounting protrusion ( 3 ) which it fastens tightly by encircling from an end, and that the ventilation duct which is fastened by the said mounting protrusion ( 3 ) is connected to a main duct by being screwed through the said mounting protrusion ( 3 ).
