ABSTRACT:
A swivel gladhand for vehicle air brake systems which includes a continuously torsioned body portion which when not in use is automatically urged to a position wherein the outlet opening therein is seated against a stop member which seals the outlet opening therein and which also includes a selectively movable locking arm which is operable to cam the body portion against the stop member to thereby positively secure the body in sealed engagement with the stop member to prevent the loss of air pressure therethrough when the gladhand is not in use.
