ABSTRACT:
A hose clamp is disclosed comprising a clamping band having open ends for lapping one end over the other end in a lapping direction and presenting a lapped portion and a lapping portion. The open ends of the band are mechanically interconnected by several outwardly extending hooks in the lapped portion. The hooks are operable to engage in corresponding apertures in the lapping portion. The clamp structure has an ear for tightening the clamping band about an object to be fastened, characterized in that at least one hook extends out of the plane in the lapping direction presenting a hook aperture and at least one corresponding aperture has a tab extending from an edge of the aperture in a direction opposite the lapping direction for abutting the hook, whereupon deformation of the ear the tab deforms towards the lapped portion forming an abutment surface for absorbing the circumferentially directed clamping forces and projects into the hook aperture for interlocking the lapped portion with the lapping portion.
