An auxiliary locking device for a sliding door is disclosed, comprising a blocking member having an upward-opening longitudinal channel near its inner side for receiving the inner frame member of the sliding door channel. At least one clamping screw protrudes through threaded hole(s) in the inner side of the blocking member into the longitudinal channel, for clamping the blocking member to the inner frame member of the sliding door with the outer portion of the blocking member protruding into the sliding door channel for blocking sliding of the sliding door, thereby preventing opening of the door past the blocking member location. A rod projects from the outer portion of the blocking member for positioning along the sliding door channel above the sliding door when the device is installed, for thereby preventing the sliding door from being lifted out of its channel for removal. The outer portion of the blocking member is provided with an upward-opening channel, and the rod is L-shaped. The rod portion constituting the base of the L-shape extends through a hole passing downwardly through the outer portion of the blocking member in the channel. Spring means are provided between the rod and the blocking member for biasing the rod into the channel, whereby the rod may be lifted from the channel against the spring force to swing the rod to project from the blocking member in either direction of the channel.
