A check rail lock with a handle pivot shaft secured for pivotal movement with respect to the housing and a cam which pivots with the shaft between an open position with the cam enclosed in the housing and a locking position with the cam extending from the housing for grasping a keeper. An axially reciprocable locking member is associated with the pivot shaft for pivoting therewith, and has a manually engageable button end projecting above the housing and a locking end within the housing. The locking end has circumferentially spaced locking surfaces, and a spring biases the member locking end into engagement with the housing. First and second locking notches in the housing receive the member locking end when the cam and handle are in the open and locking positions, respectively, and the locking notches each have a surface engaging one of the locking end locking surfaces to prevent pivoting of the locking member and pivot shaft when the member locking end is received therein.
