A measuring probe for the invasive measurement of blood parameters such as pH, PO2 or pCO2 comprises one or more optical fibers (9) in a tubing (7). These optical fibers (9) end up in sensors (8, 14, 15) which are surrounded by a sheath (2). An additional wire (5) is guided both in the tubing (7) and the sheath (2). At the proximal end of the probe, the wire (5) is connected to locking means (3) closing the sheath (2) at its outer end, whereas, at the distal end thereof, the wire (5) is fastened to the tubing (7) or to a connector (19). Therefore, this wire (5) ensures perfect strain relieving of the probe. A measuring probe of the present design guarantees complete mechanical stability and, in particular, a completely firm connection between the tubing element and the sheath. Mechanical stability is essential to insure that no part of the probe can break off or be sheared off, since this could lead to embolism and, thus, even to the death of a patient.
