Abstract
A marking device is provided so as to be movably mounted upon the mouth or open end of the barrel (1) of an explosive or propulsive driving apparatus. It comprises a flexible case (11) fixed upon an anvil (10) which is intended to transmit the energy of the piston (4) of the apparatus to a series of punches (14) disposed within the case and whose stroke is controlled by means of a damping pad (19) which is resiliently deformed during marking.
