A locking magnet closure, consisting of a first closure module and a second closure module with the following features: - comprising a magnet-keeper construction with at least one magnet in closure module 1 and a keeper or second magnet in closure module 2, wherein on closing the magnet-keeper construction pulls the closure module 1 and the closure module 2 together in closing direction x, - for opening, the closure module 1 and the closure module 2 are rotatable or shiftable in opening direction y laterally to the closing direction x, - comprising a locking device for positively locking the closure modules between closure module 1 and closure module 2, comprising - at least one spring locking element, which consists of an engaging protrusion (9a, 9b) and a spring and which is arranged in the closure module 1, and - a locking piece (7a, 7c) which is arranged in the closure module 2, wherein - on closing, the locking piece (7a, 7c) pushes the spring locking element to the side in a direction z and then positively snaps into place with the engaging protrusion (9a, 9b) and - on shifting or rotating closure module 1 and closure module 2 in opening direction y, the locking piece and the spring locking element are rotated or shifted against each other from an engagement position, in which locking piece (7a, 7c) and spring locking element are in engagement, into a non-engagement position, in which locking piece (7a, 7c) and spring locking element are not in engagement, without the spring locking element being pushed to the side, - wherein the magnet-keeper construction is dimensioned such that on closing the locking device is automatically closed by the magnetic force of the magnet-keeper construction, characterized in that - the spring of the spring locking element is a strip bent around the closing direction x and is formed and arranged such that it has a dual function, namely - that on closing the spring deflects flexurally soft in direction z and thus when snapping into place is spread in direction z, - but when applying a load on the closure against the closing direction x, the spring is flexurally rigid, such that the locking piece (7a, 7c) and the engaging protrusion (9a, 9b) are locked positively with each other. -
