Abstract
In an open hose clamp with overlapping band ends, the outer band part comprises, starting from its end, an opening, an undulation, an Oetiker ear, an aperture, and a hook, while the inner band part comprises, starting from its end, a hook for engagement in the opening, a smooth area spanning the undulation and the ear, and a tongue with an attachment which passes through the aperture. The attachment serves to guide the tongue in the aperture and thus to ensure correct mutual positioning of the two band parts, transverse to the longitudinal direction of the band, in addition to securing the hose clamp in the engaged state, and cooperating with the hook provided on the outer band part for opening the tightened clamp.
