The invention relates to a detonator system for hand grenades, having an ignition element () which after initiation triggers a delay and safety device, which, with a time delay after the initiation, fires a detonator (), which then ignites an ignition booster (), wherein the delay and safety device includes a dual safety device of two independent parts. So that the hand grenade detonator system according to the invention includes a purely pyrotechnic detonator system instead of a pyrotechnic-mechanical system, it is suggested that the delay and safety device consists of two pyrotechnic ignition delay devices with different delay times&#x2014;specifically a safety element () and a delay element ()&#x2014;wherein the delay time of the safety element () is shorter than the delay time of the delay element (), and the safety element () includes a timing composition which, once it has burned through, ignites a gas charge (), the gas of which opens blocking elements (), and the delay element () includes a firing charge, and the firing charge is only in operative connection with the detonator () after the opening of the blocking elements ().
