ABSTRACT:
Outward flanges on top of pump outlet tube include a rearward latching section. A rearwardly extending horizontal shelf is formed on the vertical tubular support of the pump body. The shroud is open-fronted and includes a top wall, connected side walls and a rear end wall with an inward horizontal shoulder. 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 onto the pump body in a simple unidirectional linear movement, the channels receiving the outward flanges respectively. The latching sections are flexed downward by the locking wedges and snap past them and the shoulder on the shroud slides under the shelf.
