A detector with a telescopic carrier/guide rod at which a measuring probe is disposed at one end, wherein the carrier/guide rod features at least two tubes longitudinally movable inside one another, in which respectively two tubes disposed adjacently in radial direction form an outer tube and an inner tube, whereby the respective outer tube at its overlapping tube end facing the measuring probe features a clamping means for engaging the inner tube. In accordance with this invention, the clamping means is formed as a clamping device that features a profile clamp with a quick-locking device. The profile clamp comprises a holding ring with two half shell-shaped clamping ring segments that are interconnected flexibly on one side and on the opposite side they can be clamped together with a clamping lever. The holding ring features ring breakthroughs and the outer tube the corresponding tube breakthroughs for the accommodation of clamping pieces that are pressed against the inner tube when clamping the clamping ring segments together under pressure. Preferably a clamping ring segment is formed on the holding ring.

1. A detector with a telescopic carrier/guide rod, comprising: a measuring probe disposed at one end of the carrier/guide rod; andat least two rod tubes being arranged longitudinally movable one within another, wherein two of said at least two rod tubes are arranged in a radial direction neighbored to each other and forming an outer rod tube and an inner rod tube,wherein the outer rod tube includes, at an overlapping tube end facing the measuring probe, a locking means for movably engaging the inner rod tube,wherein the locking means is formed as a clamping device that includes a profile clamp with a quick-action tension lock,wherein the profile clamp is immovably arranged at the overlapping rod tube end of the outer rod tube and includes a holding ring with half shell-shaped first and second clamping ring segments that are flexibly connected together at one circumferential front side of each segment and are capable of being clamped together at the other circumferential front side of each segment by means of a clamping lever, wherein the holding ring is formed cylindrically hollow and bears the clamping ring segments and wherein the holding ring is pushed on an outer surface of the respective overlapping tube end of the respective outer tube immovably, andwherein at least one of the clamping ring segments is movable with respect to the other clamping ring segment and the holding ring in the radial direction of the rod tubes. 2. The detector according to claim 1 wherein the overlapping tube end of the outer tube features at least one tube breakthrough. 3. The detector according to claim 2 wherein the clamping device features at least a clamping protrusion or a clamping piece, which is disposed radially movably in the at least one tube breakthrough and protrudes on the respective outer tube and stands adjacent inside the first clamping ring segment. 4. The detector according to claim 3 wherein the clamping protrusion or clamping piece is rigid and the first clamping ring segment presses the clamping protrusion or clamping piece when bracing the two clamping ring segments with each other under employing force against the inner tube. 5. The detector according to claim 3, wherein the holding ring features at least a ring breakthrough, which overlays at least one tube breakthrough. 6. The detector according to claim 5 wherein the clamping protrusion or clamping piece of the clamping device penetrates the tube breakthrough and the ring breakthrough together and protrudes over an outer circumference of the holding ring and braces itself inside one of the clamping ring segments. 7. The detector according to claim 6 wherein the holding ring is held by means of the clamping protrusion or clamping piece on the overlapping tube end of the outer tube. 8. The detector according to claim 1, wherein the holding ring is inside a position limit stop arranged at a face side of the overlapping tube end. 9. The detector according to claim 8, wherein the position limit stop is formed as a face-side ring collar or ring collar section, whereby the holding ring overlaps the overlapping tube end in an axial direction with a large part of length of the holding ring. 10. The detector according to claim 1, wherein at least one of the clamping ring segments is inside an alignment limit stop assigned on a face side of the overlapping tube end, which is formed as a face-side ring collar section. 11. The detector according to claim 1, wherein the first clamping ring segment is formed on the holding ring and the second clamping ring segment is connected flexibly with the holding ring. 12. The detector according to claim 1, wherein the clamping lever features a bend corresponding to the clamping ring segments. 13. The detector according to claim 11, wherein the first clamping ring segment is connected flexibly with the holding ring.
