<p>A DETECTOR FOR OVER-PRESSURE INSIDE A PIPE AND A PUMP FITTED WITH SUCH A DETECTOR The invention concerns a simpler inexpensive and small detector, particularly for use in medical pumps, for detecting over-pressure in a pipe (1) and setting off an alarm when an over-pressure is detected. Such a detector for detecting over-pressure in a pipe (1) along which a fluid (3) flows, comprises : - means (5) for deriving a fraction of the flowing fluid (3) from the pipe (1); - at least one tube (7) wherein there is fitted at least one obturating member (9); and - means (11) for detecting the displacement of the obturating member (9) in the tube (7) and for generating a signal in response to detecting displacement of the obturating member (9).
