A spring ring (41) of rectangular cross section has adjacent its ends arms which extend generally radially outwardly. The ring (41) is used to hold together two members (31, 40) in telescopic engagement by engaging in an internal groove (45) in one member and in an external groove (46) in the other. During assembly of the members the ring is located entirely in one of the grooves by a holding element (51) supported wholly by the arms on the ring. After assembly the holding element is withdrawn radially outwardly through a slot (47) in the external member. |
