Abstract

A connecting device couples an explosive charge, triggerable by electric current, to a current source. A two core electrical line has the explosive charge at one end, the current source at the other end and the connecting device in between. The connecting device includes a plug (4) with two plug pins (7,8) extending parallel to each other. In the connected state of the connecting device, a counter plug (5) matingly receives the two plug pins. The plug (4) has a cavity (14) between the two plug pins (7,8) in which a short-circuit element (11) made from a resilient metal is provided. The short-circuit element (11) is moveable relative to the plug pins (7,8) between an operative position and an inoperative position. The short-circuit element (11) extends, from its operative position, which is determined by its shape and resilience and corresponds to the disconnected state of the connecting device, into the space provided for the counter plug in the connected state of the connecting device, by a shorter distance in relation to the length of the plug pins (7,8 ), thereby electrically contacting the plug pins (7,8). In its inoperative position, the short-circuit element (11) is recessed in the cavity (14) of the plug (4) out of electrical contact with the plug pins (7,8) and abutting the front of the counter plug situated in the connecting device in its connected state.
