A probe-holder armature contains a sensor probe that is removably arranged in the forward portion of an immersion tube which is axially movable in a housing between a retracted rest position and a deployed working position. The sensor probe in its installed condition forms a medium-tight closure of the immersion tube. The immersion tube contains a removable insert which can be held in a fixed position by means of a closure member. By means of the insert, the sensor probe in its installed position is pushed forward against a forward stop of the immersion tube. A safety device prevents an axial movement of the immersion tube out of its rest position if one or more of the three components sensor probe, insert and closure member are missing.

The invention claimed is: 1. Probe-holder armature comprising: a sensor probe that is removably arranged in the forward portion of an immersion tube with a cylindrical outside surface, the immersion tube being axially movable in a housing between a retracted rest position and a deployed working position, wherein the sensor probe in its installed condition provides a medium-tight closure of the immersion tube, wherein the immersion tube has a removable insert which can be held in a fixed position by means of a closure member and by means of which the sensor probe in its installed position is pushed forward against a forward stop of the immersion tube, wherein a safety device is provided which prevents an axial movement of the immersion tube out of its rest position if one or more of the three components including sensor probe, insert and closure member are missing, characterized in that the safety device has a safety slide which surrounds the rear end of the insert and which is slidingly movable between a further forward stop and a rearward stop inside the immersion tube from a first locking position through a releasing position to a second locking position, wherein the safety slide cooperates with at least one locking member that is arranged with radial mobility in the immersion tube, wherein in each locking position of the safety slide, each said locking member sits with its inward-facing side against the outside surface of the safety slide while the outward-facing side of each said locking member engages a locking recess in the housing, and wherein in the releasing position of the safety slide each said locking member engages at its inward-facing side a circumferential groove in the safety slide, while the outward-facing side of each said locking member is freed from the locking recess of the housing. 2. Probe-holder armature according to claim 1, characterized in that the insert is configured in a tubular shape and has a front side that sits against a matching rearward-facing side of the sensor probe. 3. Probe-holder armature according to claim 1 or 2, characterized in that the closure member can be inserted at the rear end of the immersion tube and, in its installed condition, keeps the insert seated against the sensor probe and also keeps the latter seated against the forward stop. 4. Probe-holder armature according to claim 1, characterized in that the safety slide has a forward locking portion, a rearward locking portion as well as a circumferential groove around its middle, and that the safety slide is pre-tensioned against the rear end of the immersion tube by means of a first spring and that when the insert is in place, the safety slide sits against a rearward flange of the insert, wherein by means of a second spring that is arranged on the closure member, the insert is pre-tensioned against the front end of the immersion tube, with the entire arrangement working in such a way that: a) when the closure member is missing, the safety slide is in position with the forward locking portion located opposite each said locking member; b) when the insert is missing, the safety slide is in position with the forward locking portion located opposite each said locking member; c) when the closure member is in place and the sensor probe is missing, the safety slide is in position with the rearward locking portion located opposite each said locking member; and: d) in the operative state, the safety slide is in position with the circumferential groove in the middle of the safety slide located opposite each said locking member. 5. Probe-holder armature according to claim 4, characterized in that the insert, the second spring and the closure member are each equipped with a lateral opening extending over their entire respective lengths. 6. Probe-holder armature according to claims 1, 2, 4, or 5, characterized in that an anterior part of the housing includes a rinsing area with at least one inlet and a drainage outlet for a rinsing medium. 7. Probe-holder armature according to claim 6, characterized in that the rinsing area is delimited in front and back by ring seals which form medium-tight closure barriers together with the associated parts of the cylindrical outside surface of the immersion tube. 8. Probe-holder armature according to claim 7, characterized in that the immersion tube is closed off at the front end and has at least one lateral opening which, in a rinsing position of the immersion tube, lies between the forward and rearward ring seals. 9. Probe-holder armature according to claim 8, characterized in that the rinsing position of the immersion tube is identical with the retracted rest position. 10. Probe-holder armature according to claim 1, characterized in that the immersion tube has a section configured as a piston which is held in a cylindrical section of the housing with axial mobility between the retracted rest position and the deployed working position. 11. Probe-holder armature according to claim 10, characterized in that the probe-holder armature comprises a fluid-operated actuator device to drive the axial movement of the immersion tube.
