Abstract: A quick-connect-and-disconnect assembly is illustrated in a bag filter environment. The assembly is used to mount a nozzle pipe on a rectangular girder. The pipe includes a mounting clip with a body having a support foot forming an inverted L-shaped configuration to engage over an upper corner of the girder. The body engages flush against the girder. At the bottom, the clip has a latching lip to engage behind a depending flange on the girder, and the lip is urged upwardly into latching engagement by an elongated coil-spring retainer which is resiliently engaged between the support foot and the top wall of the girder. Means is provided on the flange to positively locate the nozzle pipe at the proper position along the length of the girder.
