A safety device 100 is provided for attachment to an edge of a door leaf 101 via a base plate 102. The device 100 comprises a pressure detector in the form of ribbon switches 104a and 104b, and a surface plate 106 including an opening (109,fig.4) for a lock element. The pressure detector in response to a force being applied to the device 100 issues a signal. The surface plate 106 may be received within a recess of the base plate 102 and may be configured to float relative to the base plate 102 by virtue of ribbon switches 104a,104b and protrusion 602. The safety device 100 may be sensitive to a ligature around an edge of the door leaf.
