<p>This disclosure relates generally to hose couplings useful for mining applications, more particularly to a fluid coupling capable of generally fully tightened by hand, including a visual lock for visual indication and safety when in a hand-tightened position. The coupling generally includes a male portion (110), a female portion (120), a retaining member (130) and a locking member (140, 150). The male portion passes through the retaining member, and the retaining member threadingly engages the female member. The locking member prevents unthreading of the retaining member from the female member.</p> |
