A patch panel having an array of openings therein and an adapter collar for mounting an optical fiber coupler in an opening. The collar has two body portions, one of which fits within the opening and the other of which buts against the front face of the panel. A coupler receiving opening extends through the body portions and has webs therein providing locking surfaces for the coupler. The collar is mounted and locked in the opening by means of cantilevered arms biased outward from the body portions, and a locking member is insertable between the arms and the body portions to prevent accidental or inadvertent release of the collar from the panel. |
