Connection device

A connection device as claimed in any one of the preceding claims, wherein the lugs are spaced from an inner surface of the first body.

A connection device as claimed in any one of the preceding claims, wherein the first and second bodies are coupled together, in use, with at least part of the second body received through the other open end of the first body.

A connection device as claimed in any one of the preceding claims, wherein means are provided on the exterior of the first and/or second bodies to indicate the correct relative rotational positions between said bodies to give said discrete positions respectively.

A connection device for fitting to a conduit having a groove adjacent an end thereof comprising a first tubular body having one of its ends open to receive said end of the conduit 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 conduit to retain it, in use, and respective engagement means, a second tubular body which can be coupled with the first body, the second body having a plurality of formations arranged such that with said first and second bodies coupled together and in a relative position in which said conduit is retained by the resilience alone of said lugs, the second body is relatively angularly movable from said position to two other positions respectively, in one of which said formations engage said engagement means to apply force which effects a locking of the projections to the conduit, and in the other of which said formations engage said engagement means to apply force which effects a release of the projections from the conduit thereby to allow its removal from said first body.

A connection device for fitting to a conduit having a groove adjacent an end thereof comprising a first tubular body having one of its ends open to receive said end of the conduit 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 conduit to retain it, in use, and respective engagement means, a second tubular body which can be coupled with the first body, the second body having a plurality of formations arranged such that with said first and second bodies coupled together and in a relative position in which said conduit is retained by the resilience alone of said lugs, the second body is relatively angularly movable from said position to another position in which said formations engage said engagement means to apply force which effects a release of the projections from the conduit thereby to allow its removal from said first body, and there being sealing means to seal with said conduit received in said bore, in use.

A connection device for fitting to a member having an external groove in an outer surface of part thereof 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 coupled with the first body, there being defined a minimum of two discrete relatively angularly adjusted positions between the first and second bodies when they are coupled together, said two discrete positions being any two from i) a neutral position where said member is retained by the resilience alone of said lugs, ii) an unlocked position where the projections are released from the member to allow its removal from the first body, and iii) a locked position where the projections are prevented from moving in a direction to release from the member.
