Abstract
A coupling half for interconnecting fire or other hose to a reciprocal connection mounted on another hose or on a fixed object. The coupling half includes two slots which enable the manufacture of the coupling half quickly, efficiently, and inexpensively. Only two molds are used to cast the coupling half compared with the traditional three molds. The molds are in contact with each other at three radial points with each radial point being separated by the mold cavity. Machining is greatly reduced as the coupling half is made from one piece as compared with the traditional two pieces. Slots in the locking collar enable the coupling half to be made of one piece resulting in less machining and a superior product.
