A connecting structure includes a locking device having a spring locking element and a locking piece for locking the connecting modules, and a magnet/armature structure having a magnet and an armature. The locking device and the magnet/armature structure are functionally linked by in that the magnet and the armature are displaceable, the magnet or the armature is coupled to the locking piece via a coupling device so that the locking piece, when displaced between the magnet and the armature, can be brought into a non-locking position; The magnetic force is chosen so that the connecting modules are pulled towards each other during closing, thereby pushing the spring locking element against the locking piece until it snaps into engagement and the magnetic force is weakened during release after the non-engagement position between the locking piece and the spring locking element is reached to enable separation of the modules.
