ABSTRACT OF THE DISCLOSURE The invention provides an improvement in hose clamps of the type employing a worm screw mounted in a housing which is fastened to a metal band and engages in slots in the band. A thin backing layer is laminated to the metal band of the clamp on the face that engages the article to be clamped, for example, to prevent extrusion of hose materials through the slots. This backing layer is of a thickness such that it will be stretched by the screw thread lands, but is thick enough that it will not break or crack under such treatment. It is slightly narrower than the band material, so that it can be applied without protruding and form dangerous knife edges, and is fixed to the band by means of a resilient adhesive that will permit the required deformation without separation. The screw thread lands can now be made deep enough for positive engagement in the slots and even protrude slightly from the other side. This improved clamp can be manufactured by a continuous process of drawing a strip of metal from one coil, stamping runs of slots in it, drawing a backing strip from another coil, laminating the two strips together by means of a thin double sided adhesive tape that is interposed between them, cutting the resulting laminate into suitable band lengths, and then mounting the housing and screw thereon.
