the 1 until 21 show different embodiments of a connector 10 according to the invention in different views and different degrees of detail. The connector 10 comprises at least one eccentric unit 100 and at least one spring clip 300. The eccentric unit 100 is in 1 until 3 shown in detail in isolation and is preferably formed in one piece. The eccentric unit 100 is preferably designed as a plastic injection molded part. More preferably, the eccentric unit 100 is colored red, even more preferably made of a red plastic material. The eccentric unit 100 comprises a base body 110. The base body 110 is essentially cylindrical, hollow-cylindrical and/or pot-shaped, with a casing or side wall 111 and a cover-like front or top side 112, which defines a surface or a bottom 112a. On the side opposite the top 112, the bottom 113, the base body 110 is partially open. The side wall 111 has a smooth surface. A spring seat 130 is provided in the base body 110 . The spring seat 130 is designed as a recess or as a through opening 131 . The spring retainer 130 extends from the top 112 in the direction of the underside 113. In order to make it more difficult for the spring clip 300 used to come loose from the spring retainer 130, the base body 110 has a (further) projection 140 with a base section 141 and a cap projecting transversely therefrom - Or lid portion 142 on. The projection 140 protrudes from the upper side 112 of the base body 110 in the area of the spring receptacle 130 . A gap 150 is formed between the cap or lid portion 142 and the spring retainer 130 . The cap or cover section 142 is arranged in such a way that it at least partially covers the spring receptacle 130 so that it is more difficult for a spring clip 300 that is inserted or received in the spring receptacle 130 to move out undesirably. The spring retainer 130 has an approximately C- or U-shaped opening on the upper side 112 . Correspondingly, the cap or cover section 142 is also C-shaped or U-shaped. Furthermore, the base body 110 has at least one eccentric tool holder 160 for at least temporary engagement of a tool, preferably for rotating the base body 110 about its axis of rotation A when it is received in a pot bore. The tool holder 160 is designed as a recess or as a through-opening 161 . The tool holder 160 extends from the top 112 in the direction of the bottom 113. In the exemplary embodiment according to FIG 1 until 3 the recess 161 has a rectangular opening at the top 112 . The cross section of the recess 161 changes in the direction of the axis of rotation A. The cross section tapers in the direction of the underside 113, so that a tool, for example a screwdriver or the like, is optimally seated in the tool recess 160 depending on the insertion depth into the tool holder. To manufacture a connector 10, the spring clip 300 is inserted into the spring receptacle 130. FIG. A spring clip is an example in 4 until 6 shown. The eccentric unit 100 preferably has a rotationally symmetrical outer contour, preferably in relation to the axis A, at least in the area of the lateral surface or casing or side wall 111 . On the side wall 111, a projection 190, not shown here, is formed (see 24 until 26 ).

4 shows schematically in a perspective view an embodiment of a spring clip 300, 5 schematically shows the embodiment 4 in a side view and 6 schematically shows the embodiment 4 and 5 in a top view. The spring clip 300 is designed as an elastic spring clip 300 . In this case, the spring clip 300 is preferably made of a metallic material. Other materials are possible. In one embodiment, the spring clip is made from a plastic as a plastic injection molded part. The spring clip 300 includes a base section 310. This extends between the eccentric unit 100 when the spring clip 300 is connected to the eccentric unit 100, and a component and/or a further eccentric unit 100 when the spring clip 300 is correspondingly connected to the component or the eccentric unit 100 is connected. The spring clip 300 in the in 4-6 illustrated embodiment two engagement portions 330, which is designed for engagement with the spring seat 130 of the eccentric unit 100 and / or a pot bore of the component to be connected. The engaging portion 330 projects transversely from the base portion 310 . At each end of the Grundab Section 310 an engagement portion 330 is provided. The spring clip 300 is designed here as a stamped and/or bent sheet metal part, preferably made of spring steel, with the engagement sections 330 each being bent from the base section 310 . An outer contour of the engagement section 330 is preferably U-shaped or C-shaped as a rounding 332 . In this case, the rounding 332 is rounded off to be adapted to the contour of the cup bore and/or the spring receptacle 130 for accommodation. The base section 310 has two lateral indentations or recesses 312 . These are formed on opposite sides of the base portion 310 . The indentations 312 have a different geometry. In the present case, both indentations 312 have a semi-circular geometry. The radii of the notches 312 are selected to be different from one another. The spring clip 300 preferably has a rigidity element 340, not shown here (see 23 until 23 ).

In 7-12 the spring clip 300 is inserted with an engagement section 330 into the corresponding spring receptacle 130 . Another engaging portion 330 is free. The spring receptacle 130 is dimensioned larger at least in the circumferential direction about the axis A than a width of the engagement section 330, so that the engagement section 330 can migrate in the spring receptacle 130 or is movably mounted. In 7 the engagement section 330 is located on an edge of the spring receptacle 130. The base section 310 adjoining the engagement section 330 is arranged in the area of the eccentric unit 100 between the upper side 112 and the cover section 142, so that accidental removal of the spring clip 300 is avoided or made more difficult. Cover section 142 and upper side 112 thus form an axial security in the direction of axis A (axial direction A). The eccentric unit 100 in the embodiment 7 until 12 an additional recess 180 on. The recess 180 is formed similarly to the tool holder 160 and extends from the upper side 112 to the lower side 113. The recess 180 preferably has a rectangular cross-section, but can also have other cross-sectional shapes. By inserting a tool into the tool holder 160, the eccentric unit 100 can be rotated about the axis A, in particular relative to the spring clip 300. The spring clip 300 is subjected to a force when the free end is fixed by the eccentric rotation. Here, the engaging portion 330 is moved along the spring retainer 130, as shown in FIGS 10 until 12 shown. In the 10 until 12 the engagement portion 330 rests against another edge of the spring retainer 130 .

22 shows a schematic side view of an embodiment of a spring clip 300 with a rigidity element 340. 23 FIG. 12 schematically shows the embodiment according to FIG 22 . The in the 22 and 23 illustrated embodiment of the spring clip 300 differs essentially from the spring clip 300 after 5 and 6 in that a rigidity element 340 is provided. The stiffness element 340 after 22 and 23 is designed as a bead 341. This runs longitudinally along the main extension H of the spring clip 300. The bead 341 runs approximately centrally between the two indentations 312. In the main extension direction H, the bead 341 is at a distance from the ends of the spring clip 300. The length of the bead 341 or of the rigidity element 340 is in the main extension direction H greater than the length of the larger indentation 312 in the main extension direction H. The bead 341 stands out from the spring clip surface, so that the spring clip 300 is designed to be elevated in the area of the rigidity element 340 . The elevation caused by the bead 341 is less than the material thickness of the spring clip 300 in this area.

24 shows schematically in a first side view a connector 10 with an eccentric unit 100 which has a projection 190 on the side or on the side wall 111 thereof. 25 shows the embodiment according to FIG. 1 schematically in a second side view 24 . 26 schematically shows the embodiment 24 and 25 in a perspective view. the inside 24 until 26 connector 10 shown differs from connector 10 according to 7 essentially in that the eccentric unit 100 has an integral part 190 . The molding 190 is in the in 24 until 26 illustrated embodiment as a partially circumferential projection 190. The projection 190 is arranged closer to the upper end of the base body 110 . In this case, the projection 190 runs approximately at the same distance from the upper end. The cross section of the projection 190 does not change over its length in the circumferential direction and transversely thereto. In the present embodiment, the projection 190 is in the form of an annular projection 190 .

It goes without saying that the features of the invention mentioned above can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the invention.
