The present invention relates to an optoelectronic module (M), intended to convert an electrical signal from a main electronic board into an optical signal or vice versa. It comprises integrating, into the optoelectronic module, a device for removably mounting an optical contact element, consisting of a flexible plate the flexibility of which allows it to be moved from an unlocking position in which it permits the passage of the body and of the optical ferrule of the element, to a locking position in which the latter is locked in the casing of the module, once the optical ferrule has been optically coupled to the module. Furthermore, a simple, even manual, pressure allows the plate to be moved from a locking position to an unlocking position that permits the optical element to be removed from the casing of the module.
