Abstract of the Disclosure A "bogie" is disposed to be slid within a pair of tracks on a trailer. A movable pin element is adapted to pass through openings in at least one of the rails and tracks to secure the bogie to the trailer. The pin element includes a pair of spaced sealing rings defining an annular air- tight chamber between the exterior of the pin and a surrounding housing. When the pin is extended into locking engagement with a respective opening the annular chamber serves to communicate compressed air to release the parking brakes for the wheels of the bogie. If the pin is not in position, the parking brakes in the bogie cannot be released.
