ABSTRACT:
In a pneumatic outlet a "U" shaped bail assembly is pivotally mounted on at least one end wall of the outlet. The bail assembly includes a pair of arms which extend outwardly from the end wall beyond the discharge tube of the outlet, and a body portion which extends transverse to the longitudinal axis of the discharge tube and joins the arms. A locking handle is mounted on the body portion which is movable to a locking position to maintain the end cap in engagement with the discharge tube. A locking assembly mounted on one of the arms of the bail is movable between a position blocking movement of the locking handle from the locking position and a position allowing movement of the locking handle to the unlocked position. A fastener member carried by the locking assembly is operable to fasten the locking assembly in the handle blocking position.
