A retractable landing gear (100) includes a main strut (110) having an upper end (103) that is configured to connect to aircraft primary structure and a lower end (102) configured to connect to an axle or bogie truck. An articulated stay (120) has a distal end configured to connect to the aircraft structure and a proximal end pivotally connected to a cardan pin member (150). The cardan pin member has a cylindrical portion with a first recessed annular channel (154). The cardan pin member is retained in the socket (160) by a ring assembly formed by two semi-annular ring members (155) that slidably engages the first recessed channel. The ring assembly defines a second recessed annular channel (156). A collar (157) is configured to be positioned over the second recessed channel, and to contract upon a change in temperature to lockingly engage the second recessed channel, to secure the split ring assembly in the first recessed channel.
