Abstract
An assembly unit includes an assembly part penetrated by a through opening and a cylindrical sleeve which is captively fixed in the through opening. The sleeve has at least one spring element which protrudes from an external face of the sleeve by an excess length in a non-assembled state. The excess length is dimensioned such that the spring element is elastically moved radially inward by contact with the wall of the through opening when the sleeve is introduced into the through opening, so that the spring element presses against the wall 4 of the through opening as a result of elastic restoring forces.

An assembly unit, comprising:
- an assembly part penetrated by a through opening defining a wall of said through opening;
- and
- a cylindrical sleeve being captively fixed in said through opening;
- said cylindrical sleeve having an external face and a wall;
- said cylindrical sleeve having at least one spring element being cut free from said cylindrical sleeve wall and protruding from said external face by an excess length in a non-assembled state;
- said spring element being a spring arm having an end integrally connected to said cylindrical sleeve wall and a free end pressing against said wall of said through opening;
- said spring arm having an external face and said spring arm having a protrusion disposed on said free end of said spring arm and protruding from said external face of said spring arm;
- and
- said excess length being dimensioned to cause said at least one spring element to be elastically moved radially inward by contact with said wall of said through opening upon said cylindrical sleeve being introduced into said through opening, causing said at least one spring element to press against said wall of said through opening as a result of elastic restoring forces.
