Pilferage deterrent device for box car, container or trailer doors of the type in which the device is toward the top of the door out of reach of a person standing on the ground, and only accessible to release the latch from the top, by a person standing on a loading dock or elevated platform. The latch cooperates with a keeper and both the keeper and latch are enclosed so access cannot be had to the latch to release the latch by a pole or elongated tool. A pivoted release member termed a trigger extends above a housing for the latch and is transversely pivoted to the housing and protected by the housing to prevent access to said release member from the ground. The release member has camming engagement with the latch and is operable by hand to cam the latch out of engagement with the keeper and accommodate opening of the door.
