ABSTRACT:
An engagement member, which is detachably securable to the liquid outlet nipple of a filter receiving fitting, is movably carried by a filter housing which also carries an annular seal which resides against the sealing surface of the fitting. An actuating rod extending from the engagement means is received at one end of a lever which is pivotally secured to the housing. In response to movement of the lever, the housing moves relative the engagement member and the seal is separated from the sealing surface.
