Zusammenfassung:1. A device for igniting an oxygen lance (100) of the type formed by a body (10) having one end capable of being opened for threading on the end of the lance and which comprises a fuel element and means capable of causing ignition of the fuel element, characterised in that it comprises a container (15, 115) housed axially in the body (10, 110) and closed in sealed manner at its two ends, for containing a first chemical compound (20, 120), a sealed reservoir (40, 140) containing a second chemical compound (41, 141) capable of reacting with the first while producing ignition when it comes in contact with it, and a perforation member (50, 150) capable of axial translation relative to the container (15, 115) and/or reservoir (40, 140) and capable of perforating a wall (70, 44; 170, 144) of the container (15, 115) and of said sealed reservoir (40, 140) for placing the first (20, 120) and second (41, 141) chemical compounds in contact during travel.
