A locking mechanism comprises a piston element comprising a piston groove extending in an axial direction along a radially outer surface of the piston element, a housing comprising a bore for receiving the piston element for reciprocating axial movement between a locked position and an unlocked position, a locking ball received in the piston groove and a locking ring mounted for rotational movement about the piston element between a locking position and an unlocking position, the locking ring comprising a radially inner locking ring groove, the locking ring groove having a recess formed in a radially inner surface thereof for receiving the locking ball in the unlocking position of the locking ring. The piston groove comprises a first axially extending section and a second axially extending section, the radial depth (D1) of the first axially extending section being greater than the radial depth (D2) of the second axially extending section.
