Problems solved by technology

However, the disadvantage associated with it is that the plug part has to be grasped by hand precisely on the outer circumference when the plug connection is being made, and there is a risk of accidents at this time.
The slots on the outer circumference of the plug part are usually sharp-edged, and thus there is a risk of cuts when producing the plug-in connection, since hands can get stuck in these slots

Embodiment Construction

[0026] As shown in Fig. 1, a plug 1 includes an outer sleeve 2 and an inner sleeve 3 integrally connected with it. However, the present invention is not limited to this. The plug can also be arranged in any other embodiment, in particular the outer sleeve 2 can be completely eliminated.

[0027] In the intermediate space between the outer sleeve 2 and the inner sleeve 3, an annularly surrounding receiving space 4 is provided, in which a hose end is inserted in the axial direction, and it is tightly fixed there.

[0028] However, the invention can also provide that the plug piece is formed integrally with the hose material connected to it.

[0029] In order to establish a snap connection, the plug 1 is provided with a snap spring 5 in the front area, which protrudes into the inner diameter of the plug 1 with multiple bends.

[0030] A pipe joint 6 can be inserted into the inner space of the plug 1, and a plurality of guide openings 9 distributed along the circumference are formed i...

Abstract

The invention relates to a plug-in connection provided with an angle-locking device for connecting tubular pipes and flexible hoses. The aim of said invention is to improve the design of a said type plug-in connection in such a way that it is possible to produce the angular locking device by particularly simple means, thereby avoiding any risk of an accident during operation of the plug-in connection, and to embodied said connection optionally with or without angular locking device without important transformation expenditures. The inventive connection is, therefore characterised in that it comprises a pipe insertable into internal space of a plug-in part which is provided, on the front-surface side thereof in a plugging direction, with axially oriented guiding openings, axially oriented openings and several radially extending guiding tongues which are projected inside a clear plug-in opening and disposed at an axial distance from a plug-in connection provided on said plug-in part.

Description

Technical field [0001] The invention relates to a plug connector with an angular locking device according to the preamble of claim 1. Background technique [0002] The patent application DE 102 311 114 originating from the same applicant describes a plug connector with an assembly aid, in which a plug can be combined with a pipe joint in a reasonable angular position. [0003] In the plug connector of DE 102 311 114, in order to produce an angular locking device, it is necessary to fix the radially outwardly directed individual components on the outer sleeve on the plug, which when establishing the plug connection ( When the pipe joint and the plug are combined in the axial direction, they are embedded in the associated groove on the pipe joint, so that a reasonable combination of the angle of the plug connection can be realized. [0004] However, the manufacturing of such an angular locking device is extremely expensive and increases the manufacturing cost of the plug connector ...
