ABSTRACT:
Connector/coupling for connection of conduit has hollow housing, collar with internally-directed protrusion capable of engaging the conduit, and means for fastening the collar to the housing to hold these together. A quick-disconnect coupling includes receiving piece with hollow passageway, passage portion and receiving end; on the outside about the receiving end is generally cylindrical surface with a groove of a width and depth capable of receiving a stopping object, and a part of the object resides above the outside surface; a swivel collar has a generally cylindrical receiving piece mating surface with a groove therein of a width and depth capable of receiving at least a portion of the part of the stopping object which resides above the outside surface; a connect device holds a received piece to the receiving piece; and a stopping device is a part thereof. Inside-out cutting saw may be employed to cut the conduit, for example, PVC helical hose. Handle locking device includes a support; a lever handle, with an actuating end, pivotally mounted on the support; and a locking pin, which protrudes from the support and can be drawn back toward the support by activating the lever handle to cause its actuating end to draw back the pin, and which pin can protrude enough so as to extend over a lowered receiving handle of a coupling.
