<p>1. Device for fixing a removable element (3) in a receptacle, in particular an indicator light unit in a receptacle (1) mounted on a panel (2), the element introduced into the receptacle being urged in the direction of its ejection by resilient means (4, 5) located in the receptacle (1), such as spring-loaded pistons serving to provide the electrical supply to bulbs located in a unit, the device being characterized by comprising an elastic tongue (7) connected to the wall (1a) of the receptacle (1) and directed obliquely toward the interior thereof in such a direction that the tongue yields elastically to the passage of the removable element (3) when it is introduced into the receptacle (1) and then substantially resumes its natural position, by penetrating into a recess (8) formed in the adjacent wall of the removable element (3) and then retaining the latter due to abutment of its extremity against the rear end (8a) of such recess, a clearance (10) being provided between the adjacent walls of the receptacle (1) and the removable element (3) to permit introduction between them of a blade (11) so as to displace the tongue (7) by means of such blade and so free the removable element (3), which is then ejected from the receptacle (1) by the resilient means (4, 5).</p> |
