Abstract: An angular plate for connecting channel shaped flanges at the ends of ducts and including first and second legs each having substantially planar top and bottom surfaces and with an inner end portion of the first leg joined to an inner end portion of the second leg so as to establish an angle therebetween. Defined by the inner end portions is an opening for receiving a connector, the first leg has substantially parallel inner and outer edges extending between an outer end portion thereof and its inner end portion and the second leg similarly has substantially parallel inner and outer edges extending between an outer end portion thereof and its inner end portion. The outer end portion of the first leg defines structure projecting extending transversely from at least one of the inner and outer edges of at least one of the first and second legs. The projection engages a side wall portion of the duct's transverse flange to retain the plate in a desired position prior to crimping of the flange.

Abstract: An optic fiber interconnection system including a plurality of composite fiber elements extending through openings in a housing and having end portions therein, each of said element end portions consisting of a jacketed optic fiber portion and a rigid protective shield member disposed between the optic fiber and the jacket. A holder mechanism retains the end portions of the optic fibers by clamping the jackets to the shield members and a base support means secured within the housing comprises a clamp assembly that retains the holder mechanism so as to prevent movement thereof.
