Abstract
Abstract A quickly attachable and detachable coupling for connecting a hose or the like to a fitting in a fluid tight relationship. The coupling includes a male member attached to the hose and having a pair of spaced ears and the fitting is provided with a female portion having slots to receive the ears and to produce a locking connection between the fitting and the male member upon relative rotation of the members through an approximately one quarter turn. During the turn the ears engage a cam surface to move an inner sleeve of the fitting into compressing engagement with a seal to provide a sealing fit between the sleeve and the fitting. The sleeve is also provided with a conical seat which receives an O-ring carried by the male member to provide a fluid tight connection between the male member and the fitting.
