A coupling half for interconnecting fire hose or other hose to a reciprocal connection mounted on another hose or on a fixed object. The coupling half includes two slots (14, 42) which enable the manufacturing of the coupling half quickly, efficiently, and inexpensively. Only two molds (33, 34) are us ed to cast the coupling half compared with the traditional three molds. The mol ds (33, 34) are in contact with each other at three radial points with each radial point being separated by the mold cavity. Machining is greatly reduce d as the coupling half is made from one piece as compared with the traditional two pieces. The slots (14, 42) in the locking collar enable the coupling hal f to be made of one piece resulting in less machining.
