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.
