  • a groove flank facing the second coupling element during coupling of the coupling elements has two opposite sections which are elastically movable inwardly due to U-shaped interruptions and thus resulting tongues.
  • a decoupling is prevented when the relative rotational position of the first coupling element and the second coupling element is selected so that the locking lugs do not completely overlap the inwardly movable portions of the groove flank of the locking groove.
  • a vacuum cleaner hose with a coupling element for releasable connection to a hollow connection part is known.
  • a hose sleeve is arranged, which is firmly connected to the vacuum cleaner hose.

  • the latching element can be brought into the unlocking position and into the locking position, that is to say movable relative to the connecting piece in order to enable the detachable connection between the suction hose and the vacuum cleaner part.
  • the locking element can assume further intermediate positions in which the connecting piece is likewise fixed by the locking element in the suction opening.
  • an elastically deformable support is integrally formed on the connecting piece, which is elastically deformed at least in the unlocked position of the locking element to exert at least a portion of the restoring force on the locking element.
  • the support is not formed on the locking element. Rather, the locking bearing is here only without material connection on the support.
  • the support can exert a restoring force on the latching element, by which the latching element can be brought from the unlocked position into the locking position. Because of the deformation, the support can namely return to its original shape, where it can exert the restoring force on the locking element.
  • This restoring force can allow a secure fixation of the connecting piece to the suction opening, since the restoring force advantageously acts at least on the locking element when it has been deflected from the locking position to the unlocking position.
  • the restoring force of the support can be advantageously achieved that the latching element without the action of external forces or at a restoring force counteracting resulting force, which is less than the restoring force, is in the locking position and secures the connection piece in the suction opening ,
  • Another achievable advantage of the elastically deformable support may be that the springback properties of the locking element can be assisted in the locking position by the deformable support or even completely taken over to relieve the locking element and thus to achieve a longer service life.
  • a locking element with a longer service life can fix the connecting piece advantageously more reliably at the suction opening.
  • the connection piece can be fixed by the support even more secure at the suction opening of the vacuum cleaner part, since the restoring function of the locking element of the support can be taken over at least in part and thus separated from the fixing function of the locking element. This can namely allow a support which has been optimized especially for the provision of the locking element in the locking position.
  • the inventors have recognized that the springback properties of the locking element in the locking position can advantageously also be taken over by a support which is integrally formed on the connecting piece.
  • “Integrally formed” means that the support and the connecting piece are made of a uniform material and form a common component.
  • the locking element and the connection piece are in one piece.
  • Such materials can also be used for the production of the connecting piece and thus also for the elastically deformable support, which actually do not have good spring properties.
  • the support can namely be designed so that it can still be deformed elastically.
  • a sufficiently stable connection piece as well as a sufficiently elastically deformable support can be made possible.
  • the integrally molded support can be a simplified construction of the connecting piece with fewer components, which can lead to a more stable and thus more durable connection piece.
  • the spud and the abutment may be made in a manufacturing step, e.g. be made by injection molding, easier and faster.
  • the locking element does not have to be attached to the connecting piece in a second production step, for example.

  • the integrally formed on the connecting piece locking element may e.g. be connected via a formed as a hinge hinge with the connection piece.
  • the support is elastically deformed in the locking position of the locking element.
  • the restoring force is therefore already exerted in the locking position on the locking element, so that a bias in the locked position can be generated.

This can become a permanent seat of the Lead the connection piece in the suction opening.
  • the support is elastically deformed in the unlocked position and in the intermediate positions between the locking position and the unlocking position. In this embodiment, the support in the locking position exerts no force on the locking element, so that the locking element, when it is brought by the support from the unlocked position into the locking position, can not be moved beyond the locking position.
  • the connecting piece on a stop means by which the path of the locking element is limited from the unlocked position to the locking position at the locking position. This means that the locking element can be brought from the unlocked position only to the locking position, where it is prevented by the stop means at a further movement beyond the locking position.
  • this makes possible a connecting piece in which the support is already elastically deformed in the locking position and thus exerts a restoring force on the locking element in the locking position, without the locking element being moved beyond the locking position. In such an embodiment, it can be ensured that the latching element remains in the locking position during the suction operation.
