Disclosed is a closure device for releasably connecting two parts, including a first closure part which includes a first base body, and a second closure part which includes a second base body. The first closure part and the second closure part can be attached to each other such that in a closed position the first base body and the second base body at least partly are at least positively connected with each other to support a load acting between the first closure part and the second closure part along a load direction, and holding of the first and second closure parts against each other in the closed position is magnetically supported. An engagement opening is formed on the first base body as a through opening into which an engagement portion of the second base body protrudes in the closed position.
