ABSTRACT:
A coupling for holding a clamped piece such as a large hose in a ring shaped clamping piece. The clamped piece has an external annular groove near its end. The end of the hose is placed in a ring shaped clamping piece which has a pair of locking pieces pivotally mounted therein. The clamping pieces pivot about an axis which is parallel to the central axis of the hose to be clamped. The clamping pieces have a curved and beveled clamping surface which moves into the center of the ring shaped clamping piece as they are closed. The beveled part of these locking pieces move into the external annular groove at the end of the hose to securely hold the hose in the clamping piece.
