Abstract: A pop-up guard or shield for use with a pop-up sprinkler mounted in a casing buried in the ground to protect against the entry of dirt, sand, weeds, and the like into the casing during sprinkler operation. The guard includes a spring biased sleeve which pops up together with the sprinkler during sprinkler extension to the operative position, and is retracted into the casing during movement of the sprinkler to the inoperative position.

Abstract: A coupling is provided for the repair of flexible conduit, such as garden hose, comprising a body portion having at least one nipple for insertion into the free end of the flexible conduit. A slotted collapsible collet is radially compressed by a retaining nut thereby clamping the conduit between the nipple and the collet. The collet is generally frustoconical in shape and is reversible for retaining one size of conduit when disposed in a first direction and a larger size conduit when reversed. In order to accommodate a still larger conduit, the collet can be omitted. The body can include a second nipple which can be similarly attached to the free end of a conduit to effect repair of the conduit. Alternatively, the body can include a male or female fitting, a pair of which can be joined to effect repair of a conduit, or used separately in connection with other suitable fittings, as desired.
