Claims: I claim:

1. An optical fibre end connector comprising:

a. A first connector portion receiving a first optical fibre end to which another optical fibre end is to be connected, the first optical fibre end being in said portion so that its end surface lies in a plane of a surface wall of said first connector portion;

b. A second connector portion having an inner collar, means defining a hole extending longitudinally through said collar and being eccentrically displaced with respect to the longitudinal axis of said inner collar, an outer collar, means defining a hole extending longitudinally through said outer collar and being displaced eccentrically with respect to the longitudinal axis thereof, said inner collar being rotatably received within the hole in said outer collar, the distance between the center line of the hole in said outer collar and the center line of the hole in said inner collar being equal to the distance between the longitudinal axis of said outer collar and the longitudinal axis of said inner collar, means for rotating said inner and outer collars with respect to each other, the another fibre end being fixedly positioned within the hole in said inner collar and with the end surface of the another optical fibre end lying in a plane of a surface wall of said inner collar;

c. Support means rotatably receiving said outer collar and being adjustably positioned on said first connector portion, said support means being adjustable to move said surface wall of said inner collar into flush and abutting relationship with said surface wall of said first connector portion, whereby said inner and outer collars can be rotated with respect to each other to align another optical fibre end with the first optical fibre end.

2. A connector as defined in claim 1 wherein said inner collar is of transparent material.

3. A connector as defined in claim 1 wherein the first optical fibre end is fixedly received in another inner collar, means defining a longitudinally extending hole which is eccentrically located with respect to the longitudinal axis of said another inner collar, said first optical fibre end being received in said hole and terminating at said surface wall of said first connector portion, another outer collar rotatably disposed between said another inner collar and said support means, means defining a hole extending longitudinally of said another outer collar and in which said another inner collar is received, said hole being eccentrically displaced with respect to the longitudinal axis of said another outer collar, and other means on said another inner and outer collars whereby said another collars can be rotated with respect to each other.

4. In combination an optical fibre end connector, receiving a fibre end, and an associated light source element which is supported on a base means to present a surface wall above the base, the connector comprising:

a. An inner collar, means defining a hole extending longitudinally through said collar and being eccentrically displaced with respect to the longitudinal axis of said inner collar, a outer collar, means defining a hole extending longitudinally through said outer collar and being displaced eccentrically with respect to the longitudinal axis thereof, said inner collar being rotatably received within the hole in said outer collar, the distance between the center line of the hole in said outer collar and the center line of the hole in said inner collar being equal to the distance between the longitudinal axis of said outer collar and the longitudinal axis of said inner collar, means for rotating said inner and outer collars with respect to each other, the fibre end being fixedly positioned within the hole in said inner collar and with the end surface of the optical fibre end lying in a plane of a surface wall of said inner collar;

b. Support means rotatably receiving said outer collar and being positioned on said base means adjacent said light source element to position said surface wall of said inner collar into flush and abutting relationship with said surface wall of said light source element, whereby said inner and outer collars can be rotated with respect to each other to align the optical fibre end to be perpendicular to the surface of said light source element.
