1. A system for monitoring a connection (1) between two tube elements (2, 3) of a medical tube conduction system said system comprising:

  • a first sensor element (4) provided in the region of the connection (1) on a first one of said two tube elements,a second sensor element (6) provided in the region of the connection (1) on a second of the two tube elements,the first sensor element (4) having at least one permanent magnet (5) generating a magnetic field,the second sensor element (8) being a magnetic field response signal transducer formed by one of a magnetically actuable electrical contact and an electronic sensor responsive to a magnetic field,with the second sensor element being positioned adjacent to the first sensor element and being actuated by the magnetic field of the permanent magnet of the first sensor element when the two tube elements of the medicinal tube conduction system are connected to one another, and with the second sensor element being deactivated, when the connection of two tube elements has become loose and wherein the two sensor elements (4,

         6) are separated from each other by more than a maximum predetermined amount,a monitoring and indicating device (10) connected to the second sensor element (6) for generating at least one of an acoustic and optical alarm signal when said second sensor element (6) is deactivated.
