Abstract

A pyrotechnic device comprises a receptacle which contains a charge of pyrotechnic material and an electric fuse to initiate the charge. The receptacle is formed of a plastics housing which has an area formed of lines of weakness adapted to rupture on activation of the pyrotechnic material and a closure having an integrally moulded projection which defines a screw-thread, electric contacts being associated with the projection and trapping the bared ends of wires associated with the fuse.
