The housing part includes a basic part and an insert part. The basic part is releasably connected with a form fit to the insert part via a latching connection. The latching connection holds the insert part releasably and is formed by a C-shaped spring clip which is seated on the outside of the basic part and engages with at least one latching extension radially through an orifice of the basic part into a circumferential latching groove of the insert part.
CROSS REFERENCE TO RELATED APPLICATIONS The application claims priority to PCT/EP/2006/062940 filed on Jun. 6, 2006 and German Utility Model DE 20 2005 009 018.2, filed Jun. 9, 2005.
SUMMARY OF THE INVENTION The object on which the present invention is based is to improve a connection device of the type mentioned, such that the assembly of the individuals parts is simplified and a simple manual releasability of the previously plugged-in plug portion detained via the clamping ring is ensured. While at the same time there is high reliability against unwanted release.
As may be gathered from FIGS. 11 to 14, the spring clip 24 comprises a C-shaped spring-elastic annular portion 32 and of preferably two latching extensions 26 lying essentially diametrically opposite one another. The annular portion 32 is of essentially strip-shaped design and extends in the circumferential direction over an angle of about 270� according to FIG. 11. An orifice of about 90� therefore remains, with the result that it is possible in a simple way to place the spring clip 24 onto the basic part 18 and also in a simple way to remove it from the latter, in each case in a radial direction, said spring clip at the same time being spread open elastically. The latching extensions 26 may themselves extend, for example, over about 60� in the circumferential direction. On their front sides facing the plug-in side of the reception orifice 4, the latching extensions 26 have oblique faces 34, in such away that, when the insert part 20 is being introduced into the basic part 18, the latching extensions 26 are urged radially outward via the oblique faces 34 and subsequently latch into the latching groove 30 as a result of the spring elasticity of the annular portion 32. The spring clip 24 is preferably seated with its annular portion 32 in an outer annular groove 36 of the basic part 18. In a preferred embodiment, in this case, there is provision for the latching extensions 26 to be designed or arranged asymmetrically in relation to the annular groove 36 and to the annular portion 32 in the axial and/or circumferential direction, in such a way that the spring clip 24 can be placed onto the basic part 18 in only one correct orientation with respect to the oblique faces 34. In this case, of course, the radial orifices 28 of the basic part 18 are adapted correspondingly to the arrangement or configuration of the latching extensions 26.
As may be gathered, further, from FIG. 7, the inner cone 16 of the insert part 20 preferably comprises two axially adjacent inner cone portions 16 a and 16 b with different cone angles. The first inner cone portion 16 a, remote from the plug-in side, has a first, flatter cone angle α1, while the second inner cone portion 16 b following in the direction of the plug-in side is designed with a second, steeper cone angle α2. According to FIGS. 8 to 10, the clamping ring 8 correspondingly has an outer cone 54 with two axially adjacent outer cone portions 54 a and 54 b in adaptation to the inner cone portions 16 a, 16 b of the insert part 20. In the preferred exemplary embodiment, the first cone angle α1 lies in the range of 10� to 25�, in particular at about 15�. The second cone angle α2 preferably lies in the range of 40� to 50�, in particular at about 45�.
