<p>Connection between tubes is made by having one tube end formed as a sleeve, the other end as a key section. Through a lateral aperture in the key section, a flat sealing strip is tangential inserted in the cavity between sleeve and key. Thin metal tube ends connection, includes key section (1) and sleeve section (2), which when they enter into each other, forms a cavity (3) which may be filled with a sealing strip (4) and synthetic resin. The e.g. rubber strip (4) is cut and fitted (5) by pressure application to the tube lip.</p> |
