Abstract
A fluid coupling wherein a tubular coupling member has a first terminal sealingly engageable with an end of a first conduit and a second terminal sealing engageable with an end of a second conduit. The end of the second conduit has a radially outwardly extending retaining flange and the coupling member has a set of radially movable resilient arms which engage the flange when the second terminal is in proper engagement with the end of the second conduit. The arms can be prevented from becoming accidentally disengaged from the flange by one end portion of a sleeve which is reciprocable along and surrounds the coupling member. The sleeve can be releasably locked in a release position in which the arms are free to become disengaged from the flange and/or in a locking position in which the sleeve prevents disengagement of the arms from the flange. The device for locking the sleeve can comprise a clamp which is more or less permanently installed in the sleeve or a clamp which can be completely disengaged from the coupling member and is not connected to the sleeve. A spring can be provided to bias the sleeve to the locking position. The clamp can be omitted if the locking device comprises one or more cams on the coupling member and a follower for each cam; such follower or followers are provided in the sleeve.
