摘要

The flanged mounting pin has a metallic spring sleeve (2) with a longitudinal slit (3) through it, with a flanged edge (4) at one end extending radially outwards. The sleeve mantle is distorted into the interior of the sleeve (2) close to the flanged edge (4) near the longitudinal slit (3), to give shaped zones (5) on both sides of the slit (3) towards the interior of the sleeve (2).
