Abstract

A connection fitting (1) for the attachment of oblong structures, for example of cables (2), hoses, tubes, corrugated hoses or the like, to an opening (3), in particular, for passing through such an opening (3) while at the same time being attached is provided. The opening (3) involves a hole, a drill hole, or other opening in a wall (4), for example of a housing. The connection fitting (1) is constructed as a plug-in fitting, i.e. is readily affixed to the opening (3) by axial insertion into it. For this it has an attachment projection (5) which is subdivided by axial slits into retaining tongues, which have radially projecting retaining projections (8) on the outside that extend behind the edge (3a) of the opening (3) when the attachment projection (5) is inserted into the opening (3), such that they yield somewhat radially to the inside during insertion and after being stuck through, automatically move again radially outwardly. By an axial movement of the connection fitting (1) opposite its plug-in direction, the retaining tongues (7) can in turn be deformed in the radial direction against the oblong structure or a cable (2) that is to be affixed and then clamped onto it. Thus, on the outside of the opening (3), a stopper (9) is provided so that the connection fitting (1) is supported on the outside. The sheath that has the stopper (9) has a support (11), which extends axially into the opening (3) and which in the assembly position engages on a partial area of the outside of the retaining tongues (7) of the attachment projection (5), and during an axial movement of the attachment projection (5) and the retaining tongues (7), impinges a conical or tapering area of the outside of the retaining tongues (7) in such a way that the retaining tongues (7) are pressed together in the radial direction so that a contact of the retaining tongues (7) with the edge (3a) that is engaged behind is avoided or if necessary done with a considerably less force than is applied for a radial deformation of the retaining tongues (7).
