<p>There is presented a valve (50) comprising a body (52) having a conduit (54) therethrough and a bore (56) therein intersecting the conduit (54). The valve (50) further comprises a plug (60) for disposition in the body (52). The plug (60) includes stem (62), handle (64), gate (66) and base (70) portions. The gate portion (66) is provided with a hole (68) therethrough and is rotatably movable between a position wherein the hole (68) is in alignment with the conduit (54) and a position wherein the hole (68) is at least in part removed from alignment with the conduit (54). The valve base portion (70) is provided with leaf springs (72) extending therefrom and having hook portions (74) on free ends thereof. In assembly of the valve (50) the hook portions (74) are deflected inwardly, when the plug (60) is inserted into the body (52) by a body shelf portion (90) extending inwardly of the bore (56). The hook portions (74) are adapted to spring outwardly upon passage of the hook portions (74) over the shelf portion (90), the hook portions (74) being thereby captured under the shelf portion (90), such that the plug (60) is prevented from substantial axial movement in the body (52). <IMAGE></p> |
