Abstract: A box is provided for receiving a removable element. The box is a generally rectangular box fitted with a tilting cam of cut-out sheet metal situated in the rear portion of the box body, the tilting cam having an actuation end and an ejection end situated on either side of a central portion of said cam for the purpose of ejecting the removable element when the cam is tilted about its central portion. The box body has in the rear portion of its top face a tab including a base extended by a tongue that extends parallel to said top face while being spaced apart from said top face, together with a lug projecting from the top face and situated facing a free end of the tongue. The tilting cam is secured to the box body by snap-fastening, having its central portion engaged firstly between the tongue and the top face of the box body, and secondly between the lug and the base.
