A fiber optic connector includes a plurality of alignment sleeves ( ) that each lies in one of the passages ( ) of a connector body ( ), with each alignment sleeve being easily replaceable. Each alignment sleeve lies in a mount sleeve ( ), with each mount sleeve having a front end with an inner flange ( ) that prevents forward movement of the alignment sleeve. Each mount sleeve has a more rearward outer flange ( ) forming a forwardly-facing shoulder ( ). A retainer ( ) includes resilient tines ( ) that abut the forwardly-facing flange shoulder to prevent forward movement of the mount sleeve, but with the tines being expandable by a special tool ( ) so the mount sleeve and alignment sleeve can be removed and replaced.

A retainer ( ) at the rear of each passage ( ) that holds an optical fiber terminus ( ), abuts the rear end ( ) of a spring to normally retain the terminus while allowing its removal, with the retainer being rugged, easily manipulated, and of small diameter to allow numerous passages to lie close together. Each retainer has a primarily cylindrical outer surface ( ) but with a pair of projections ( ). The rear portion of the passage has a first part ( ) through which the retainer can be slid forwardly while the retainer is in an initial rotational orientation. A third passage part ( ) receives the retainer and allows it to be turned from the initial orientation ( A) to a lock rotational orientation ( B). A second passage part ( ) that lies between the first and third passage parts, allows the projections to move rearwardly into recesses ( ) that prevent rotation of the retainer and that have forwardly-facing shoulders ( ) that abut the retainer to limit its rearward movement.

A bi-directional tamper resistant temperature adjustment controller interface comprises a control dial having an interior face wherein a cylindrical center boss extends therefrom, said cylindrical center boss having a substantially annular cross section, and a central axial bore adapted to receive a rotatable control member and an exterior side wall of the boss has formed therein a first and a second ring of inline recessed notches adapted for resistively engaging a deflecting member. In one embodiment of the invention the first and second ring of inline recessed notches are a first and second ring of directional serrations wherein the first ring of serrations are angularly directed in a first direction to resist rotation of the dial in one direction of rotation and the second ring of serrations are angularly directed in a second direction to resist rotation of the dial in an opposing direction of rotation.

A tamper resistant temperature dial and associated method of use is disclosed. This includes a temperature adjustment device associated with a controller for a heating device that includes a rotatable dial for setting temperature in the heating device, a ring that is operatively attached to the rotatable dial or the controller, wherein the ring includes a plurality of notched portions, and a resilient detent having a first portion engagable with at least one of the plurality of notched portions on the ring, a second portion for releasably applying pressure to the resilient detent for disengaging the first portion of the resilient detent from the at least one of the plurality of notched portions on the ring and having a third portion that is operatively attached to the attached to the controller or the rotatable dial. The heating device can be either electric or gas.

A thermocouple mounting assembly is provided. A plurality of retainers includes portions that are interengageable, some portions carried by a body and some portions carried by a thermocouple assembly to effect releasable mounting of a thermocouple assembly to a body. The retainers are constructed and shaped to provide for their formation by a molding process such as die-casting or investment casting, eliminating or substantially eliminating the need for machining of the retainer components. Preferably, there is an audible sound, e. g. , click, present to signify when the retainers are interengaged.
