Abstract: A connecting apparatus includes a first connecting part, which has a first basic body and at least one engagement protrusion arranged rigidly on the first basic body, and a second connecting part, which is attachable to the first connecting part in a closing direction and which has a second basic body with an engagement portion arranged rigidly on the second basic body. The first connecting part has a first magnetic device and the second connecting part has a second magnetic device. The first magnetic device and the second magnetic device interact in a magnetically attracting manner along the closing direction to assist the attachment of the first connecting part and the second connecting part to each other. The first connecting part has a blocking portion which is designed, in the connected position, to interact with the second connecting part in order to block the engagement of the engagement portion with the at least one engagement protrusion counter to an engagement direction.

Abstract: Provided is a closure device including a first closure part that includes a locking element, a force transmission element operatively connected to the locking element, which can be loaded along a force direction, and an actuating element movable relative to the locking element, and a second closure part that includes an engagement element. The locking element and the engagement element can be attached to each other for connecting the first closure part and the second closure part to each other and are connected to each other in a closed position. In the closed position, when the force transmission element is loaded along the force direction, the locking element is loaded in a locking direction towards contact with the engagement element by the action of force of the force transmission element. The actuating element can be actuated in order to adjust the locking element against the locking direction.

Abstract: A closing device has a first closing part which has a housing and a blocking piece disposed on the housing; a second closing part which has a sprung locking element which at least in portions is configured so as to be spring-elastic; and a magnetic element which acts between the blocking piece of the first closing part and the second closing part and causes a magnetic attraction force between the blocking piece of the first closing part and the second closing part. The first closing part for closing the closing device is capable of being placed on the second closing part in a closing direction. The blocking piece and the sprung locking element in a closing position are mutually engaged such that the first closing part in the direction counter to the closing direction is locked in relation to the second closing part.
