Abstract

A pyrotechnical dowel has a shank and a deformation chamber located at the forward end of the shank. The chamber contains a blasting cap. Triggering of the blasting cap takes place from the rearward end of the shank by means of a triggering tool which is introduced into a longitudinal duct within the shank and which comes into direct contact with a bottom of the blasting cap.
