Claim:
1. An arrangement for monitoring at least one of an infeed of a fluid via tubing to a patient or an outfeed of the fluid from the patient, the monitoring arrangement comprising: a device configured to monitor a pressure in the tubing such that if there is a change in pressure that exceeds a preset limiting value due to a tractive stress on the tubing, it is concluded that a cannula on the tubing is slipping out; a guiding piece taking a form of an annular body configured to loosely fix intersecting portions of a segment of the tubing which forms an eye, which intersecting portions pass through a same opening of the guiding piece, the eye forming a loop which contracts under the tractive stress; and a securing piece configured to fix a portion of the segment of tubing forming the eye which is situated between the intersecting portions, such that the portion of the segment of tubing forming the eye which is situated between the intersecting portions is kinked and does not slip through the guiding piece when the loop tightens.
