LOCKING DEVICE FOR AN AIR BRAKE HOSE COUPLING MEMBER

摘要

A locking device for a pair of mating air brake hose coupling members includes a housing with a first aperture for attachment to one air brake hose coupling member and a second aperture for attachment to a hose support member which is adjusted to provide a predetermined clearance between the air brake hose coupling and a rail track. A locking pin is reciprocally disposed within the housing and is being urged by a resilient member in one direction for preventing undesirable complete rotational uncoupling of such pair of mating air brake hose coupling members. The locking pin is manually movable in the opposite direction during coupling and uncoupling under normal operating conditions.
