Vibration damping device for detachably connecting two parts with a guided unlocking sleeve

A two-part (MP1, MP2) spring (7) clip fixture secures cabin panels to an aircraft inner fuselage wall, or panel to a vehicle bodywork. The fixture (MP1) has an oscillation dampener ring (4) made of esp. elastic material with an aperture holding a bush (1). The bush receives the interlocking bush head (1-1) which forms the second part (MP2) of the fixture. The oscillation dampener ring (4) has a peripheral groove (N) which receives the rim of the opening in the second part (MP2). The spring (7) is linked to the oscillation dampener ring (4).
