1. A closure device, comprising
a first closure part, which includes a base element and at least one closure element movable relative to the base element with a form-fitting portion arranged thereon, and
a second closure part, which includes an engagement element with an engagement portion formed thereon,
wherein in an open position of the closure device the first closure part and the second closure part are separated from each other and can be attached to each other along a closing direction for closing the closure device, and
wherein the form-fitting portion of the at least one closure element can be brought into engagement with the engagement portion of the engagement element in an engagement direction substantially transversely to the closing direction, so that in a closed position the first closure part and the second closure part are held at each other along the closing direction,
further comprising a first magnetic element arranged on the at least one closure element of the first closure part and a second magnetic element arranged on the engagement element of the second closure part, wherein in the open position the at least one closure element of the first closure part takes a first position relative to the base element, and on closing the first magnetic element and the second magnetic element cooperate in a magnetically attracting way so that the at least one closure element is moved with the form-fitting portion in the engagement direction out of the first position relative to the base element in order to bring the form-fitting portion into engagement with the engagement portion of the engagement element,
wherein the first closure part includes a locking element which in the open position acts on the at least one closure element with a locking portion in order to hold the at least one closure element in the first position.
