  • the closure parts are generally designed as rigid parts.
  • the second assembly for example, can be a flexible part, such as a textile part.

  • a locking lug 28 on the body 20 of the first closure part 2 is also in engagement with an associated locking opening 300 on the body 30 of the second closure part 3 in order to secure the transverse position of the closure parts 2, 3 to one another.
  • the connecting part 4 has a fastening device 41 which is designed to produce a positive connection with the second closure part 3.
  • the fastening device 41 has two form-locking elements 412 extending parallel to one another, between which the body 30 of the second closure part 3 can be pushed along a fastening direction U perpendicular to the closing direction X, as can be seen from Fig.6 in conjunction with Fig. 10 to 13A , 13B is visible.
  • the body 30 lies between the form-locking elements 412 and is in contact with a stop element 413 via a front edge, so that the body 30 assumes a defined position between the form-locking elements 412 along the fastening direction U.
  • the position of the body 30 in relation to the connecting part 4 is secured via a locking element 414, which is deflected when the body 30 is inserted and, in the fastened position, is in engagement with a rear edge of the body 30, so that the hold of the second closure part 3 along the fastening direction U on the connecting part 4 is secured.
  • connection of the second closure part 3 from the connecting part 4 can be released by pushing the second closure part 3 counter to the fastening direction U out of engagement with the form-locking elements 412.
  • connection via the form-locking elements 412 in the fastened position can be designed such that in the event of excessive loading, for example when a tear-off force is applied to the second closure part 3 that exceeds a limit force, the second closure part 3 can be disengaged from the form-locking elements 412 in the vertical direction. In this way, an emergency release can be provided in the event of excessive loading.
  • a closure device 1 has closure parts 2, 3, identical to those previously described in the embodiment according to Fig. 1 to 5A-5C Functionally and structurally, the closure parts 2, 3 are similar in the embodiments according to Fig. 14 to 16 and Fig. 1 to 5A-5C , whereby the closure part 2 is shown in Fig. 14 to 16 is not shown.
  • a fastening device 41 is integrated into a housing part of an associated second assembly 6, so that the second closure part 3 can be fastened directly to the second assembly 6 via the fastening device 41.
  • the fastening device 41 has engagement elements 410 which are arranged within an opening 400 formed in the housing part of the assembly 6 and project inward into the opening 400.
  • the engagement elements 410 can be brought into engagement with the engagement openings 31 on the body 30 of the closure part 3 to produce a bayonet connection, in order to thereby produce a positive connection between the engagement elements 410 and the body 30 of the closure part 3, as described above with reference to Fig. 1 to 5A-5C has been described.
  • the closure part 3 is thus fixed directly to the associated second assembly 6 via the bayonet connection.
  • no separate connecting part 4 is provided for the second assembly 6, but the fastening device 41 is integrated directly into the second assembly 6, for example a housing part of the second assembly 6.
  • the second closure part is detachable from the connecting part, which enables maintenance, renewal or restoration of the second closure part by the second closure part being able to be detached from the connecting part and replaced or repaired.
  • the detachable connection also enables easy recycling, as the second closure part or at least parts of the second closure part, for example the magnetic element of the second closure part, can be reused.
  • the connecting part can be manufactured easily and inexpensively and can also be adapted to the associated assembly.
  • the connecting part can, for example, be manufactured together with the associated assembly by attaching the connecting part to the assembly during production or, if necessary, by manufacturing it integrally with the second assembly. Only then is the second closure part attached to the connecting part so that any impairment of the second closure part, for example due to Heat exposure to the magnetic element of the second locking part is avoided during production of the assembly.
