Abstract: A novel locking system of the type which has very useful properties and at the same time can be produced cost-effectively, and is therefore suitable to be a mass-produced product, particularly for use in motor vehicles and building fixtures.

Abstract: 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.
