ABSTRACT:
An inexpensive and easy to use coupling for connecting one end of a corrugated flexible hose to a meter or distributor outlet, or to another hose on an implement such as an air drill or seeder. Two generally semi-cylindrical portions are molded as a single unit with integral hinge and locking structure. The inner surface of the cylindrical member is corrugated to correspond to the corrugations on the flexible hose, and an end portion of the coupling device includes an annular groove which mates with a flange on the outlet. The locking structure automatically latches as the semi-cylindrical portions are closed around the hose and the flange.
