ABSTRACT:
A pump and filter assembly comprising a filter cover secured onto a filter body by a locking ring. A one-piece latching mechanism, integral to the locking ring and composed of flexible material, biases a latching end of the latching mechanism against the locking ring, causing the latching end of the latching mechanism to project through a slit in the locking ring into a notch on the outside of the filter body when the filter body is completely threadably engaged with the locking ring. The latching portion of the latching mechanism is easily biased away from the slit and the notch, facilitating disengagement of the locking ring from the filter body and filter cover. The entire latching mechanism is itself easily removed from the locking ring, facilitating repair or replacement of the latching mechanism.
