The invention concerns a locking device consisting of a key and of a lock. Inside the lock is a shaft (1) that has at least two diametrically opposed cams (4 & 5 ) mounted on it. The key can be positioned against one end (2) of the shaft in such a way that it cannot rotate in relation thereto. Inside the body (6) of the lock are blocking or barricading elements (9 & 10) that can slide or pivot radially in the unbarricaded state and that are subject to springs (40) that force them radially inward. The blocking elements are barricaded by means of several blocking pins (11) that block the sliding blocking elements or operate in conjunction with them by means of special blocking extensions on them to provide a blocking action. The blocking pins are subject to spring (12 or 60) that force them into the blocking position. Barricading is deactivated by means of tappets on the key that can be adjusted with respect to their effective length and that act either directly on the blocking pins or on intermediate complementary pins (27) and force them back. The locking device can also have means of blocking the blocking elements (9 & 10) in the outwardly displaced or pivoted position, the open position.
