The invention provides a damping mechanism which comprises a damper; and a coupling mechanism. The coupling mechanism comprises a coupling member which is pivotally attached to the damper and has a pivot bearing for pivotally connecting the coupling member to a structure when in use; and a fitting which can be engaged with the coupling member to couple the fitting with the damper and disengaged with the coupling member to decouple the fitting from the damper. More, the coupling member has a pair of parallel planar faces which taper outwardly from the pivot bearing to a convex curved edge, an upper edge and a lower edge; and a first and a second recess formed in the convex curved edge, a rib between the first and the second recesses and, a third recess formed in the lower edge.
