The invention concerns an improved hose clamp consisting of an outer annular tightening band (1) which is provided with a tightening device (3, 4), and of a resilient band (2) which extends along the inner face of the tightening band (1). The resilient band is provided with two axially spaced, inwardly directed peripheral beads (6) which extend around the resilient band (2). Intermediate the beads (6) the resilient band (2) is formed with an outwardly directed ridge (7) in abutment against the inner face of the tightening band (1). By means of a number of openings (8), the ridge (7) is divided into a number of bridges (9) which interconnect the beads (6) with one another around the resilient band (2). These bridges (9) are arranged to allow bead movability in the radial as well as axial directions.

An improved hose clamp consisting of an essentially rigid tightening band (1) which is bent to annular shape with its ends extending in an overlapping position through a tightening device (3, 4) to tighten the hose clamp about an object, such as a hose (10) of an elastic material, and also of a resilient band (2) which is positioned internally of the tightening band (1), said resilient band being formed with two axially spaced, inwardly directed peripheral beads (6) which extend around the resilient band, and also with an outwardly projecting ridge (7) intermediate said beads, said ridge (7) abutting against the internal face of said tightening band (1), characterized by the provision in said resilient band ridge of a number of openings (8) dividing said ridge (7) into a number of bridges (9) interconnecting said peripheral beads (6) around the resilient band, said bridges arranged to impart to said beads some movability radially as well as axially.
