Zusammenfassung:	The firing arrangement for a grenade has a delay type fuse (9,16) and a percussion shock detector (6). They work on an interruptor of an explosive chain to open to the chain, only after a predetermined time. The fuse has inside an opening (7) a delay filling (9). The filling is set off on launching the grenade and burns for the desired time. At the end of this time it displaces a first blocking assembly (11,12,13) of the interruptor to open it. The blocking assembly is a piston (11) sliding in the opening (7) with a head (13). L'INVENTION CONCERNE UN BOUCHON ALLUMEUR DE GRENADE A SECURITE DE LANCEMENT ET FONCTIONNEMENT REGLABLE.LE BOUCHON COMPREND UN DISPOSITIF FUSANT 9, 16 A RETARD PYROTECHNIQUE ET UN DISPOSITIF DE PERCUSSION A DETECTION DE CHOC 6 AGISSANT L'UN ET L'AUTRE SUR UNE MEME PIECE 19 DITE INTERRUPTEUR DE CHAINE PYROTECHNIQUE, LE PREMIER POUR PROVOQUER L'OUVERTURE DE LADITE CHAINE PYROTECHNIQUE AU BOUT D'UN TEMPS DE FONCTIONNEMENT PREDETERMINE ET LE SECOND POUR INTERDIRE SON OUVERTURE DANS LE CAS OU LE DISPOSITIF DE PERCUSSION SE DECLENCHE AVANT LA FIN D'UN TEMPS DE SECURITE PREDETERMINE, INFERIEUR AUDIT TEMPS DE FONCTIONNEMENT.
