Abstract:
1. A connection device for fitting to a member having an external groove in an outer surface of one part thereof, the device comprising a first tubular body having one of its ends open to receive said part of said member in a bore communicating with said open end, the first body having a plurality of resilient lugs with respective projections at or adjacent their ends for reception in said groove in said outer surface of said member to retain said member, in use, and a second tubular body which can be movably coupled with the first body, there being defined two discrete relatively angularly adjusted positions between the first and second bodies when they are coupled together, said two discrete positions being i) a neutral position where said member is retained in the first body against withdrawal by the resilience alone of said lugs in the absence of any movement between the first and second coupled bodies, and ii) an unlocked position where the projections are released from the member to allow its removal from the first body in the absence of any axial displacement of the member as the first and second bodies are moved relative to each other.
