  • the locking leg is moved due to its elastic abutment on the wall portion of the bag and due to a friction occurring during an unwanted disassembly in a mounting-preventing clamping position.
  • the locking leg can be rigid or bendable, or have a friction increasing clamping edge or be designed as a clamp eccentric.
  • the locking leg Due to the inventive extension of the locking leg this is able to exert a latching or clamping locking action, which ensures the closure member in question against unwanted disassembly.
  • the training is such that disassembly without special aids is not possible and therefore a loss of the or the closure elements is effectively prevented.
  • the free end of the locking leg can serve as a locking element or clamping element, which automatically when mounting in its release position elastically displaced and due to the elasticity automatically causes the jamming or latching locking.
  • the end portion is shaped so that it forms a three-point system with the two wall portions.
  • a stable positioning of the end portion is ensured in the pocket, which allows taking into account the effective against the wall portions of the bag clamping action stable seating of the end portion in the pocket and due to the clamping action and the resulting frictional engagement the desired securing the end portion in the pocket also guaranteed.
