Patent ID: 7500791

Claim:
A method for longitudinally securing a light guide to a light source, the light guide having an axis and an end termination having a predetermined size and the light source having an opening with an axis for receiving the end termination, the method comprising: expanding the opening from a rest condition, corresponding to a nominal condition of the opening with no user input and no light guide engaged with the opening, to an open condition; coaxially inserting the light guide into the opening; shrinking the opening to a closed position to directly, without any other elements interposed between said light guide and said opening, grip the light guide with a first gripping pressure limiting axial motion of said light guide relative to said opening; increasing the gripping pressure to a second gripping pressure, greater than said first gripping pressure, further limiting axial motion of said light guide relative to said opening to lock the opening in a locked condition; and maintaining the second gripping pressure without continued user input.
