A lock assembly (100) comprising a first handle mechanism (20), a second handle mechanism (20'), a bolt (55) for latching and/or locking engagement in a respective or complementary recess; and a bolt retractor mechanism (40) for moving the bolt (55) from an extended position for engagement in the recess to a retracted position for disengagement from the recess. The first handle mechanism (20) comprises a first handle (21) that is manually movable about a handle axis (22) and a first force providing part operatively associated with the first handle (21) for movement in response to movement of the first handle (21), and the second handle mechanism (20') comprises a second handle (2 Γ) that is manually movable about a handle axis (22) and a second force providing part operatively associated with the second handle (2Γ) for movement in response to movement of the second handle (2Γ). The bolt retractor mechanism (40) includes: a retractor member (43) configured to pivot about a retractor axis (42) for moving the bolt (55) between the extended position and the retracted position, a first force receiving part (44) configured for operative connection or engagement with the first force providing part of the first handle mechanism (20) for receiving force to pivot the retractor member (43) about the retractor axis (42), and a second force receiving part (47) configured for operative connection or engagement with the second force providing part of the second handle mechanism (20') for receiving force to pivot the retractor member (43) about the retractor axis (42).
