ABSTRACT:
Outward flanges on top of pump outlet tube include a rearward latching section. The shroud is open-fronted. Extending downward along the top wall of the shroud are a pair of opposed channels to the rear of which are unitary downward locking wedges. In assembly, the open-fronted shroud is moved forward from the rear onto the pump body in a simple uni-directional linear movement, the channels receiving the outward flanges respectively. The wedges forcefully engage and pass the latching sections and take positions in front of them to block retreat of the shroud.
