  • the repeal of the latching connection 13e / 3c between the first locking part 13 and the housing 3 can then be canceled after the change of the label carrier 1 by a relative rotation of the first locking member 13 about the axis XX of the sensing device T by the corresponding locking elements 13e and 3c disengaged to be brought.
  • the frictional locking connection 13f / 17h is doing canceled with the aid of the manual force tool.
  • the pressure sensing device according to the invention then passes through the restoring action of the compressed return spring 18 back into the position shown in FIG. 13, from which it is represented by a further relative rotation of the first locking member 13 about the axis XX of the sensing device T back into the in Fig. 12, operational position can be brought.
  • the invention is not limited to the combination of features defined in claim 1, but may also be defined by any other combination of particular features of all individually disclosed features. This means that in principle virtually every individual feature of claim 1 can be omitted or replaced by at least one individual feature disclosed elsewhere in the application.
