## Abstract

In an open hose clamp, the end of the outer one of the mutually overlapping clamping band portions terminates in a tongue. For tightening the clamp, the tongue has a toothed region which cooperates with a toothed region on the inner clamping band portion. The inner clamping band portion has with guide brackets that surround the tongue at least in part.

## Claims

### Claim 1

A hose clamp comprising:
a clamping band having ends which overlap one another in a closed condition of the clamp thereby forming an inner and an outer clamping band portion,
wherein the outer clamping band portion terminates at one of the ends in a tongue which has a width reduced with respect to that of a main portion of the outer clamping band portion,
wherein the tongue carries on an inner side, at least one inward facing projection cooperating with at least one outward facing projection provided at the inner clamping band portion for tightening the clamp,
wherein the inner clamping band portion has retainers which are closed at their outer sides and surround the tongue at least in part, and
wherein the retainers are stamped from the material of the clamping band, and material webs left between adjacent ones of the retainers are enlarged in width thereby reducing gaps in the clamping band formed by the stamping so that the gaps are smaller than the retainers.

### Claim 2 (depends on 1)

The hose clamp of claim 1, wherein the at least one inward facing projection comprises a plurality of inward facing teeth.

### Claim 3 (depends on 1)

The hose clamp of claim 1, wherein the retainers extend at an angle to the longitudinal direction of the clamping band.

### Claim 4 (depends on 1)

The hose clamp of claim 1, wherein each of the inner and outer clamping band portions has a formation for engagement by a tightening tool, and the formation on the inner clamping band portion is disposed adjacent to the at least one outward facing projection.

### Claim 5 (depends on 4)

The hose clamp of claim 4, wherein the formation provided on the inner clamping band portion has a pair of hooks disposed on either side of the tongue.

### Claim 6 (depends on 5)

The hose clamp of claim 5, wherein a further retaining structure for the tongue is provided on the side of the hooks facing the end that terminates the inner clamping band portion.

### Claim 7 (depends on 4)

The hose clamp of claim 4, wherein the tightening tool comprises pliers.

### Claim 8 (depends on 1)

The hose clamp of claim 1, wherein the end of the inner clamping band portion terminates in an inner tongue of a width reduced with respect to the main portion of the clamping band, and a step corresponding to the thickness of the inner tongue is formed in the outer clamping band portion.

### Claim 9 (depends on 8)

The hose clamp of claim 8, wherein a region of the clamping band adjacent to the step has a window corresponding to the width of the inner tongue.

### Claim 10 (depends on 9)

The hose clamp of claim 9, wherein the window is covered by a remaining material strip of the clamping band which extends along an arc having a curvature corresponding to that of the hose clamp when tightened.
