Hose coupling

Claim 1

A hose coupling comprising a central unitary coupling body open at each end thereof and having a central external cylindrical surface portion, a pair of like coupling means, each adapted to be secured to a hose and cooperable with each end of the coupling body, an annual groove formed in each coupling means, a pair of diametrically opposed latches pivotally mounted on said central coupling body at each end thereof, a hook portion formed on each of said latches, spring means mounted in said unitary central coupling body urging each of said latches into engagement with a said annular groove when said coupling means is pushed inwardly into an open end formed in said central coupling body, said latch means lying within recesses in said central coupling body and having an external surface commensurate with the external surface of the central coupling body and lying thereon so that no portion thereof extends beyond the central coupling body surface when said central coupling body is in latched engagement with its cooperating coupling means, the opposite ends of the said central coupling body being frustoconical with the outer diameter of the apex equal to the outer diameter of the coupling means and the outer diameter of the base equal to the outer diameter of the central cylindrical portion of the coupling body whereby smooth and unobstructed conical transitional surfaces are provided for the coupling to prevent its impalement when in use on obstructions such as curbs, doors, or the like.
