ABSTRACT:
Hose clamps fashioned from wire have radially outwardly extending end portions which are connected to overlapping clamping member which is placed in compression when the hose clamp is tightened. In some embodiments the clamping member is a helically wound coil spring which may be integral with the wire or may be a separate element. In other embodiments, the clamping member is a screw-like member. Threads for receiving the screw may be integrally formed in the wire. Various connectins may be provided to attach the free end of the screw to the other end of the tightenable wire. For example, pins and cooperating holes may be for this purpose. If desired, multiple wire members can be serially connected to one another. And, the wire can be doubled on itself with a threaded lug or a hook being formed at the bent end. Coil springs and bights can be used to accommodate dimensional variations in the member being clamped. In addition, the screws can be designed so that there are one or more detent positions for each revolution of the screw.
