A clamp structure of the open type with mutually overlapping inner and outer band portions, in which two ears are provided disposed diametrically opposite one another and at least the outer band portion is provided with an additional opening on the side of its ear opposite the free end of the outer band portion to balance the clamp structure when installed on an object to be fastened thereby. For larger clamp sizes, the inner band portion may also be provided with an opening located on the side of the outwardly extending hooks of the mechanical interconnection opposite the free end of the inner band portion. The inner band portion may additionally be provided with an outwardly extending hook adapted to engage in the opening provided in the outer band portion so as to keep the two band portions axially aligned. Elastic stretchability may be imparted to the clamping band by one more sections having non-rectilinear lateral band portions on both sides of the center longitudinal clamping band plane, whereby one or more of such sections replace one or more of the openings. |
