Connection housing for optical fibre, suitable for a standard connector shape (211, 311), comprising two portions (101, 102, 104) able to be assembled together along an axial direction by the open ends thereof, said housing comprises: a. a cylindrical housing arranged inside a base carried by the first (102, 104) of the two portions, said housing comprising a first tapered portion; b. an insert able to slide inside said cylindrical housing, comprising a second tapered portion able to cooperate with said first tapered portion, and further comprising a radial play with respect to said housing; c. a connection interface fixed to said insert and comprising ci. a sleeve for receiving endpieces of a first pair of connectors of the standard shape cii. functional surfaces able to cooperate with the functional surfaces of the connection support of said first pair of standard connectors; ciii. a reference surface; d. elastic means able to apply an axial force directed towards the second portion of the housing on the insert; e. a receiving interface fixed inside the second portion of the housing and comprising: ei. an axial passage for a second pair of standard connectors; eii. a receiving surface able to axially stop the reference surface of the connection interface of the first portion when the two portions are connected; where eiii. when the connection interface penetrates or accosts or the receiving interface, the resistance force to the introduction of the connection interface into said receiving interface pushes back the insert by compressing elastic means in such a way that the tapered portions of the insert and of the base are no longer in contact and the floating of said insert in the cylindrical housing of the base, allows for the relative orientation of the receiving interface and of the connection interface; f. means for coupling able to render integral the two portions of the housing and to apply the reference surface of the connection interface against the receiving surface. a. a cylindrical housing arranged inside a base carried by the first (102, 104) of the two portions, said housing comprising a first tapered portion; b. an insert able to slide inside said cylindrical housing, comprising a second tapered portion able to cooperate with said first tapered portion, and further comprising a radial play with respect to said housing; c. a connection interface fixed to said insert and comprising ci. a sleeve for receiving endpieces of a first pair of connectors of the standard shape cii. functional surfaces able to cooperate with the functional surfaces of the connection support of said first pair of standard connectors; ciii. a reference surface; ci. a sleeve for receiving endpieces of a first pair of connectors of the standard shape cii. functional surfaces able to cooperate with the functional surfaces of the connection support of said first pair of standard connectors; ciii. a reference surface; d. elastic means able to apply an axial force directed towards the second portion of the housing on the insert; e. a receiving interface fixed inside the second portion of the housing and comprising: ei. an axial passage for a second pair of standard connectors; eii. a receiving surface able to axially stop the reference surface of the connection interface of the first portion when the two portions are connected; where eiii. when the connection interface penetrates or accosts or the receiving interface, the resistance force to the introduction of the connection interface into said receiving interface pushes back the insert by compressing elastic means in such a way that the tapered portions of the insert and of the base are no longer in contact and the floating of said insert in the cylindrical housing of the base, allows for the relative orientation of the receiving interface and of the connection interface; ei. an axial passage for a second pair of standard connectors; eii. a receiving surface able to axially stop the reference surface of the connection interface of the first portion when the two portions are connected; where eiii. when the connection interface penetrates or accosts or the receiving interface, the resistance force to the introduction of the connection interface into said receiving interface pushes back the insert by compressing elastic means in such a way that the tapered portions of the insert and of the base are no longer in contact and the floating of said insert in the cylindrical housing of the base, allows for the relative orientation of the receiving interface and of the connection interface; f. means for coupling able to render integral the two portions of the housing and to apply the reference surface of the connection interface against the receiving surface.
