The invention relates to a device for locking the end positions of movable switch parts and, in particular, the movable point ( ) of a frog, in which two relatively axially displaceable parts are capable of being displaced into a position coupled with each other in a positive manner in at least one direction of movement, wherein the relatively displaceable parts are comprised of a tube ( ) and a rod ( ) guided within the tube ( ) and are at least partially arranged in a stationary outer tube ( ), whereby locking members ( ) cooperate with the relatively axially displaceable parts ( ) as well as the outer tube ( ) and are capable of being displaced in the radial direction into a locking position in a recess or inner annular groove ( ) of the outer tube ( ). Said device is designed such that the outer tube ( ) is comprised of two tube parts ( ) capable of being axially displaced within each other, and that each tube part carries at least one recess or inner annular groove ( ).
