Closure device having a rotary element

A closure device, comprising:

• a first closure part and a second closure part, the first closure part and the second closure part being attachable to each other along a closing direction and held on one another in a closed position, wherein the first closure part and the second closure part are releasable from each other for opening the closure device,
• wherein the second closure part includes a housing element with a bearing opening and a rotary element rotatably mounted in the bearing opening of the housing element,
• wherein the rotary element is operatively connected to a pulling element and, in an open position of the closure device, is rotatable with respect to the housing element of the second closure part along a winding direction,
• wherein the first closure part includes a first toothing device and the second closure part includes a second toothing device formed on the rotary element,
• wherein, in the closed position of the closure device, the first toothing device and the second toothing device are in engagement with each other in such a way that a rotation of the rotary element with respect to the first closure part is blocked in at least one direction of rotation along the winding direction, and
• wherein the first closure part and the second closure part each include at least one magnetic element for providing a force of magnetic attraction on placement of the closure parts against each other.
