Abstract

A plug-on body which can be plugged onto a device for administering a settable dose of an injectable product, the plug-on body including a first body section extending axially in the direction of a plug-on body axis for fixing the plug-on body to a casing of the device, a shifting stopper formed by the first body section and operating by positive lock for axially fixing the plug-on body with respect to at least one shifting direction, a rotational stopper formed by the first body section and operating by positive lock for fixing the plug-on body against rotating, and a second body section extending behind the first body section in the direction of the plug-on body axis, wherein the second body section is formed by a shell body for at least one of shielding a dosing element of the device which serves to set the dosage and forming an adjustment stopper operating by positive lock for the dosing element.

c) a rotational stopper, formed by the first plug-on body section and operating by positive lock, for fixing the plug-on body against rotating;

d) and a second plug-on body section, extending behind the first plug-on body section in the direction of said plug-on body axis, wherein said second plug-on body section is formed by a shell body for at least one of shielding a dosing element of the device which serves to set the dosage and forming an adjustment stopper, operating by positive lock, for the dosing element.

2. The plug-on body as set forth in claim 1, wherein the second plug-on body section is formed by a shell body.

3. The plug-on body as set forth in claim 2, wherein said shell body is a sleeve body.

4. The plug-on body as set forth in claim 1, wherein the first plug-on body section is formed by a shell body provided with a recess which forms at least one of the shifting stopper and the rotational stopper, extends in the direction of the plug-on body axis and is formed as one of a breach in the shell body or a cavity on an inner surface area of the shell body.

5. The plug-on body as set forth in claim 4, wherein said recess of the first plug-on body section extends as far as a facing side of the plug-on body.

6. The plug-on body as set forth in claim 5, wherein the recess is a blind recess.

7. The plug-on body as set forth in claim 5, wherein the recess comprises a widening at a distance measured in the direction of the plug-on body axis and wherein at least one of two walls of the plug-on body, facing opposite each other axially and limiting said widening, forms the shifting stopper.

8. The plug-on body as set forth in claim 7, wherein a side wall of the recess forms the rotational stopper of the first plug-on body section.

9. The plug-on body as set forth in claim 4, wherein the first plug-on body section is provided with at least one latching element for establishing a latching connection with the casing of the device.

10. The plug-on body as set forth in claim 9, wherein said at least one latching element is formed in the recess.

11. The plug-on body as set forth in claim 1, wherein the plug-on body is transparent in at least one area, the transparent area for forming a viewing window being arranged such that once the plug-on body has been fixed, a dosage scale of the device can be read.

12. The plug-on body as set forth in claim 11, wherein said viewing window forms a reading-glass.

13. A plug-on body which can be plugged onto a device for administering a settable dosage of an injectable product, said plug-on body comprising:

a) a first plug-on body section, extending axially in the direction of a plug-on body axis, for fixing the plug-on body to a dosing element of the device which serves to set the dosage;

b) a shifting stopper, formed by said first plug-on body section and operating by positive lock, for axially fixing the plug-on body with respect to at least one shifting direction;

c) a rotational stopper, formed by the first plug-on body section and operating by positive lock, for fixing the plug-on body against rotating; and

d) a second plug-on body section, extending behind the first plug-on body section in the direction of said plug-on body axis, wherein said second plug-on body section forms an adjustment stopper, operating by positive lock with the casing, for said dosing element.

14. The plug-on body as set forth in claim 13, wherein the second plug-on body section is formed by a shell body.

15. The plug-on body as set forth in claim 14, wherein said shell body is a sleeve body.

16. The plug-on body as set forth in claim 13, wherein the first plug-on body section is formed by a shell body provided with a recess which forms the shifting stopper and/or the rotational stopper, extends in the direction of the plug-on body axis and is formed as a breach in the shell body and/or a cavity on an inner surface area of the shell body.

17. The plug-on body as set forth in claim 16, wherein said recess of the first plug-on body section extends as far as a facing side of the plug-on body.

18. The plug-on body as set forth in claim 17, wherein the recess is a blind recess.

19. The plug-on body as set forth in claim 17, wherein the recess comprises a widening at a distance measured in the direction of the plug-on body axis and wherein at least one of two walls of the plug-on body, facing opposite each other axially and limiting said widening, forms the shifting stopper.

20. The plug-on body as set forth in claim 19, wherein a side wall of the recess forms the rotational stopper of the first plug-on body section.

21. The plug-on body as set forth in claim 16, wherein the first plug-on body section is provided with at least one latching element for establishing a latching connection with the casing of the device.

22. The plug-on body as set forth in claim 21, wherein said at least one latching element is formed in the recess.

23. The plug-on body as set forth in claim 13, wherein the plug-on body is transparent in at least a local area, the transparent area for forming a viewing window being arranged such that once the plug-on body has been fixed, a dosage scale of the device can be read.
