A latching mechanism for use with a plug-in cartridge or the like. The latching mechanism comprises a body portion; a pair of walls extending from the body portion; a camming portion; and an actuating portion. The walls of the latching mechanism are snap locatable onto pivot pins on a face plate of the plug-in cartridge, or the like, and thereby allow the latching mechanism to pivot on the face plate. Furthermore, the walls of the latching mechanism have apertures which are snap locatable onto detents on the face plate thereby resiliently latching the latching mechanism when it is fully inserted into a cabinet. The camming portion projects from the latching mechanism and is used for engaging a cooperating projection on a cover of the cabinet. The camming portion and the actuating portion cooperate to function as a lever, the camming portion being engageable with an inside surface of a mating apparatus to establish a first engagaement about which the latching mechanism is levered to overcome an insertion force, and engageable with an outside surface of the mating apparatus to establish a second engagement about which the latching mechanism is levered to overcome an extraction force. When the latching mechanism is in a latched position the latching mechanism is flush with the face plate. To disengage the latching mechanism from the detents, the actuating portion must be levered out from the face plate by a blade, or the like.
