Mounting unit and method of making same

Abstract

A mounting unit includes a mounting part having an activation side defining an opening leading to a throughbore. A fixing part is insertable into the throughbore is fastenable to the mounting part, the fixing part including: a head which allows a fastening of the fixing part to the mounting part; a shaft adjoining the head on a top end thereof and being insertable with its bottom portion and with radial play into the throughbore; fixing projections disposed at the bottom portion of the shaft and extending beyond a cross section of the shaft in a plane perpendicular to the shaft longitudinal axis, the fixing projections being effective over an entire circumference of the shaft for fastening the fixing part to the mounting part; and an undercutting space disposed between the head and the fixing projections. A holding sleeve is adapted to be fastened to the mounting part and to surround the shaft and the fixing projections with radial play after the fixing part is inserted into the mounting part. The sleeve includes a holding collar at a top end thereof having a plurality of holding projections distributed across its circumference which allow the fixing part to pass therethrough unhindered during its insertion into the mounting part. The holding projections are deformable such that they project into the undercutting space in a radially inward direction after an insertion of the fixing part into the mounting part thereby lockingly opposing a loosening of the fixing part with respect to the mounting part.
