Hose clip

Claim 2

A hose clip comprising an annularly formed outer tension band having ends which are of substantially stiff material, connected to a tensioning device for regulating the girth of the clip, and an inner band of a spring material mounted inside the outer tension band, the inner band being formed with at least two axially-spaced inwardly directed beads having concave cross sections, which beads are spring-biased radially and which beads are ridge-like and extend substantially annularly along the inside of the inner band, the inner band also having an axial, convex central zone between said beads, said central zone engaging against a straight inner portion of the tension band whereby, on tightening about an elastic hose, the hose clip axially compresses the hose between the beads simultaneously as the beads compress the hose radially.

Claim 3

A hose clip as in claim 1 wherein the inner band, which forms an insert, extends axially outside the outer tension band on either side thereof, said inner band being formed with radially outwardly directed edges for axially positioning the bands relative to each other.

Claim 4

A hose clip as in claim 1 wherein the thickness of the inner band is less than that of the outer tension band.

Claim 5

A hose clip as in claim 1 wherein the ends of the inner band overlap.

Claim 6

A hose clip as in claim 4 wherein the tensioning device of the outer band comprises a worm screw accommodated in a screw housig and wherein the ends of the inner band overlap at the position separate from that of the screw housing.

Claim 7

A hose clip comprising an outer tension band having opposite ends; an adjustable tensioning device cooperating with said opposite ends for regulating the girth of said outer band; an inner band in the form of a spring metal strip mounted inside said outer band, said inner band having at least two radially inwardly directed beads which are axially spaced apart and extend annularly along the inside of the inner band said inner band also including a convex bulge protruding radially outward between said beads into contact with the inside of said outer band, said inner band extending axially on either side of said outer band and having radially outwardly directed edges which embrace said outer band, the construction being such that upon tightening of the clip about an elastic hose by tightening of said outer band by manipulation of said tensioning device, said bands will compress the hose radially and simultaneously compress the hose axially between said beads.

Claim 8

A hose clip comprising an outer tension band having opposite ends; an adjustable tensioning device cooperating with said opposite ends for regulating the girth of said outer band; an inner band in the form of a spring metal strip mounted inside said outer band, said inner band having at least two radially inwardly directed beads which are axially spaced apart and extend annularly along the inside of the inner band said inner band also including a convex bulge protruding radially outward between said beads into contact with the inside of said outer band, said inner band extending axially on either side of said outer band and having radially outwardly directed edges which embrace said outer band, the construction being such that upon tightening of the clip about an elastic hose by tightening of said outer band by manipulation of said tensioning device, said bands will compress the hose radially and simultaneously compress the hose axially between said beads.
