Abstract: A tamper-proof lock includes: a housing, shaft/handle, cam, lever, spring, and plate. The shaft is pivotally mounted in a housing orifice, with the cam pivotally mounted to the shaft. The cam has first and second shaped openings at first and second respective radial positions, and an arcuate recess. The lever is secured to the shaft, and has a protrusion that alternately engages each of first and second ends of the arcuate recess to respectively/selectively drive the cam to rotate/counter-rotate in first and second directions, into locked and unlocked cam positions. The spring biases the plate for a protrusion thereon to be respectively received within each of first and second shaped cam openings, when aligned therewith at those cam positions, and for a curved surface of the plate to be correspondingly received within first and second curved cam recesses, respectively, when aligned therewith, which facilitate withdrawal of the plate protrusion.

Abstract: An optical module, used for lighting and/or signalling purposes for a motor vehicle, includes a support delimiting a compartment for receiving a functional component such as a fan. A clamping element, preferably produced as a single part, can be used to block an opening of the compartment and lock the component in its operational position. The clamping element, separate from the support and provided with two arms, is engaged and clipped on against at least one engaging protrusion formed laterally on the support in order to achieve the locking. An elastic return effect of at least one of the two arms allows the clamping element to be engaged at the rear of the protrusion and held in place. For unlocking, a flexible actuation portion formed in the clamping element can be actuated in order to move one of the two arms outwards and allow unclipping to take place.
