ABSTRACT A "clip-on" device for detecting whether or not an optical fibre is carrying a light signal includes bending means for controllably causing a portion of a fibre to be subjected to a gradually increasing amount of deformation and a first detector for detecting light escaping from the bent fibre. A second detector detects when the fibre has been subjected to a predetermined maximum amount of deformation. If light is detected by the first detector a signal is sent to a control unit which stops the bending means from further increasing the amount of fibre deformation and gives a first output indication. If the second detector detects that fibre deformation has reached the predetermined maximum amount and no light signal has been received, a signal is sent to the control unit which stops the bending means from further increasing the amount of fibre deformation and gives a second output indication. Preferably, the bending means is in the form of a frustom of a cone which has in its curved surface a helically extending groove and which can be helically driven about its axis. The leading end of an optical fibre is initially disposed in the groove at the larger end of the mandrel and the mandrel is rotatably driven about its axis.
