Abstract: A clamp fitting (1) for a hose end (80) is described which employs a hose clamp (2) and at least one support element (4). The support element (4) includes a substantially U-shaped section in which the hose source (2) is held. An extension section (10) is located at this U-shaped section, said extension section including at least one engagement element (14, 15). The end of the at least one engagement element (14, 15) has sharp edges. The ends can also be designed in pointed fashion. If the clamp fitting is attached to a hose, the engagement elements penetrate the hose by way of these ends. This arrangement prevents further slipping of the clamp fitting attached to the hose.

Abstract: Plug connection arrangement for connecting a first hollow body, such as a pipe socket, to a second hollow body, such as a hose, by means of a clip. The first hollow body has a pre-assembly portion, on which the clip can be pre-assembled in a pre-assembly position. The first hollow body has a final assembly portion to which the clip is secured in a final assembly position. The pre-assembly portion and the final assembly portion are offset in the peripheral direction of the first hollow body, so that the clip can be transferred from the pre-assembly position into the final assembly position by twisting relative to the first hollow body.
