A LOCKING DEVICE FOR A SLIDING DOOR Abstract of the Disclosure A sliding door of the type employed in public transport vehicles and driven by an electric motor comprises at least one door-leaf coupled with a nut mounted on an endless screw which is driven in rotation in order to open and/or close the door. The nut is displaced in transla- tional motion within a guide which prevents rotational motion. The locking device comprises means for interrupting the translational displacement of the guided nut at the end of travel and for permitting annular rotation of the nut with the endless screw, means for limiting the angular displace- ment of the nut and finally means for limiting the transla- tional motion of the nut if it is displaced along the endless screw and no longer engaged in the guide. -1-
