Hose clamp for clamping a hose on a pipe by means of a spring band whose end sections in the spread-apart state are lockable and a release device for the hose clamp

1. A hose clamp for clamping a hose on a pipe, the hose clamp comprising:

a spring band bent to a ring shape and comprising end sections configured to positively lock one another in a locking position when the spring band is in a spread-apart position widened past a nominal diameter of a hose against a spring force of the spring band, wherein the locking position of the end sections is releasable such that the spring band contracts about the hose;

wherein the end sections are positioned laterally adjacent to one another in an axial direction of the hose clamp and have a first edge and a second edge facing one another in the axial direction of the hose clamp;

wherein the first and second edges have at least one laterally projecting tooth, respectively;

wherein, in a radial view onto the hose clamp, the at least one tooth of the first and second edges is substantially triangular, respectively;

wherein both of the flanks of the at least one tooth of the first and second edges are slanted toward a free end of the end section, respectively; and

wherein the at least one tooth of the first edge in the spread-apart position of the spring band is adapted to engage the at least one tooth of the second edge by axially bending the end sections toward each other against the spring force of the spring band.

2. The hose clamp according to claim 1 , wherein the at least one tooth of the first and second edges are bent in a radial direction of the hose clamp so that the at least one tooth projects past an annular periphery of the spring band, respectively.

3. A hose clamp for clamping a hose on a pipe, the hose clamp comprising:

a spring band bent to a ring shape and comprising end sections configured to positively lock one another in a locking position when the spring band is in a spread-apart position widened past a nominal diameter of a hose against a spring force of the spring band, wherein the locking position of the end sections is releasable such that the spring band contracts about the hose;

wherein the end sections are positioned laterally adjacent to one another in an axial direction of the hose clamp and have a first edge and a second edge facing one another in the axial direction of the hose clamp;

wherein the first and second edges have at least one laterally projecting tooth, respectively,

further comprising a connecting member holding the end sections together in the spread-apart position of the spring band, wherein the connecting member has three parallel legs,

wherein a first one of the three legs projects into an opposed tooth gap and a second one and a third one of the three legs are pressed against an axially outer edge of the end sections.

4. The hose clamp according to claim 3 , wherein, in a radial view onto the hose clamp, the at least one tooth of the first and second edges is rectangular, respectively.

5. The hose clamp according to claim 3 , wherein the connecting member has a grip.

6. The hose clamps according to claim 5 , wherein the grip is annular.

7. A release device for releasing a spread-apart hose clamp, the hose clamp comprising a spring band bent to a ring-shape and comprising end sections configured to positively lock one another in a locking position when the spring band is in a spread-apart position widened past a nominal diameter of a hose against a spring force of the spring band, wherein the locking position of the end sections is releasable such that the spring band contracts about the hose, wherein the end sections are positioned laterally adjacent to one another and have a first edge and a second edge facing one another in an axial direction of the hose clamp, wherein the first and second facing edges have at least one laterally projecting tooth, respectively; the release device adapted to be locked on the first one of the end sections and comprising:

a slide and two presence sensors for detecting a presence of a hose in the hose clamp;

wherein the slide is configured to engage, in a radial direction of the hose clamp, the second one of the end sections and wherein a detection range of the presence sensors is located adjacent to an axially outer edge of the first and second end sections and wherein a sliding movement of the slide, when a hose has been detected in the hose clamp by the presence sensors, is released by a certain amount and the second end section is entrained, wherein, after the slide has travelled the certain amount, the teeth of the first and second end sections are moved radially out of engagement.

8. The device according to claim 7 , configured to magnetically lock on the first end section.

9. The device according to claim 7 , wherein the slide is configured to be electromagnetically actuated.

10. A hose clamp for clamping a hose on a pipe, the hose clamp comprising:

a spring band bent to a ring shape and comprising end sections configured to positively lock one another in a locking position when the spring band is in a spread-apart position widened past a nominal diameter of a hose against a spring force of the spring band, wherein the locking position of the end sections is releasable such that the spring band contracts about the hose;

wherein the end sections are positioned laterally adjacent to one another in an axial direction of the hose clamp and have a first edge and a second edge facing one another in the axial direction of the hose clamp;

wherein the first and second edges have at least one laterally projecting tooth, respectively;

wherein both flanks of the at least one tooth of the first and second edges are slanted toward a free end of the end section, respectively;

wherein each end section has a tooth-free section between a section of the end section having at least one tooth and the free end of the end section, and wherein the tooth-free section has a width narrower in the axial direction than a width of the section of the end section having the at least one tooth.
