<p>The device (1) has a detection unit (3) i.e. feeler, for detection of an animal. A housing (4) contains a firing electric circuit comprising a firing contactor controlled by the detection unit. The housing comprises an interrupting unit allowing selectively for interrupting or restoring continuity of a section of the circuit. A cover (9) is fixed on the housing and the detection unit in a covering position in which continuity of the section is established. The cover is removable so as to be separated from the housing in a withdrawal position in which continuity of the section is interrupted.</p> |
