ABSTRACT:
Mounted adjacent the end of a plastic hose remote from its connection to a kitchen sink faucet or other such water source is an improved hose-pinching clamp assembly of the present invention which enables effective watering of remotely located plants. The significant improvement in performance is that the clamp, during normal watering service, is confined to providing a desirable "soft" stream by a pliable sleeve or tube in covering relation over the clamp, said tube maintaining the clamp partially closed upon the hose so as to restrict flow to said "soft" stream. Prior art clamps, in contrast, can inadvertently be opened too much, and may therefore operate with a watering stream that splashes or otherwise is unsuitable for the purposes intended.
