Abstract
A device for locking the end positions of movable railway switch parts in which two parts axially displaceable relative to each other are displaced into a position coupled to each other for movement in at least one direction. The relatively displaceable parts, formed by a tube and a rod guided within the tube, are arranged at least partially within a stationary external tube. Locking elements comprising balls cooperate with the axially displaceable parts and the external tube and are displaceable radially into a lock position within a recess of the external tube. The balls are surrounded by a ring resiliently held in a position having an outer diameter smaller than, or equal to, the outer diameter of the axially displaceable tube retained in a peripheral groove of the tube. The balls are arranged in openings in the tube between the rod and the ring.
