<p>An open self-aligning clamp, the overlapping inner and outer band portions of which are adapted to be mechanically connected before tightening about the object to be fastened thereby by a plastically deformable so-called "Oetiker" ear; the mechanical connection includes only two outwardly extending hooks in the inner band portion operable to engage in apertures provided in the outer band portion, whereby one of the hooks is a tab-like guide hook pressed out of the clamping band in a transversely extending plane intersecting the clamping band in the transverse direction while the other hook is a cold-deformed support hook, the inner and outer band portions are reliably guided relatively to one another during tightening of the clamp by a tab-like member pressed out of the inner band portion in such a manner that it extends in the longitudinal direction and can slidably extend within a narrow longitudinal slot in the center area of the outer band portion.</p> |
