Abstract
A detonator is intended to be installed in a chamber equipped with a blockable access opening. The detonator includes a member for initiating a pyrotechnic chain and a casing for confining the initiation member. The casing includes, facing the initiation member, a port for igniting a pyrotechnic charge placed in the chamber outside the casing. The detonator also includes a shutter for blocking the port which can be moved between a retracted position clear of the port and a position for blocking the port. A device for operating the shutter keeps the shutter in the retracted position when access to the chamber is blocked, and in the blocking position when access to the chamber is open.
