The objective of the invention is to replace the rope bar of the door evacuation slide with individual connections. According to a preferred embodiment, the mechanism for arming/disarming an aircraft door evacuation slide (1, 15, 16) includes two releasable connectors (21) disposed to either side of the base of the door and each includes two half connectors (21s, 21i), a so-called upper half connector (21s, 41, 4a, 42) rigidly connected to the door (1) and having an attachment device (33) for attachment to the slide, and a so-called lower half connector (21i) fixed to the cabin floor (6). Each upper half connector (21s) includes a movable inner part controlled by a ring (43) and housed in the corresponding lower half-connector (21i). The mechanism can also include an electric motor coupled to two rods (31), each rod (31) being capable of rotating the control ring (43) of each upper half connector (21s) between two angular positions: an armed position and a disarmed position.
