Abstract

The open hose clamps are fitted with a tightening device in the form of an oetiker 24 called an Oetiker helix. The tightened condition is locked by means of a 15,23 tooth-shaped section, which is welded. The other side Outside of the area in the ear, the top of the ear 24, far from the end of the clamping band outside. In a locked state The ears have been loosened. So that the hose clamp does not lose the clamping function Even if the ear protruding straight outwards 24 has been disfigured Width of the escape bar The precipitate in the area of the auricle will be reduced. That has been compared Otherwise, then with full width Clamping bar
