A detachable hose coupling includes an improved female coupler piece. The female piece is generally cylindrical female sleeve piece having a pair of coaxially aligned bored open surfaces which are in opposing generally equidistant positions and displaced from a vertical plane passing through a central longitudinal axis of the female sleeve piece. A grooved surface extends partially into an outer surface of the female sleeve and extends between the bored open surfaces. A male piece is provided and a staple is provided for use in connecting the male piece to the female piece, wherein the staple fits through the bored open surfaces and seats in the grooved surface.

1. A detachable hose coupling, which comprises:a generally cylindrical female sleeve piece having a pair of coaxially aligned bored open surfaces which are in opposing generally equidistant positions and displaced from a vertical plane passing through a central longitudinal axis of the female sleeve piece, a first grooved surface extends partially into an outer surface of said female sleeve and extends between said bored open surfaces, and a longitudinal axial open surface extending through said female sleeve piece in communication with said bored open surfaces; a generally cylindrical male piece having a first end which is of a size and configuration to permit insertion into said female sleeve piece, a longitudinal axial open surface extending through said male piece and further having an external recessed surface portion which when said male piece is inserted into said female sleeve piece is generally alignable with said bored open surfaces to provide an interconnecting open surface through said detachable hose coupling, said male piece having a second end configured to fixably connect to a flexible hose; a generally U-shaped staple configured with two opposing arms and an interconnecting transverse member, wherein said arms are configured to be received through said bored open surfaces of said female piece and about said recessed surface of said male piece while said transverse member generally seats within said first grooved surface to interconnect said male piece and said female piece along lines of contact between said first grooved surface, said transverse member, said arms, said bored open surfaces and said recessed surface; and further including a second grooved surface which extends partially into an outer surface of said female sleeve and which intersects said first grooved surface to permit access between said transverse member and said first grooved surface in a manner to enable insertion of a pry tool there between for separation of said staple piece and said female piece, wherein said second grooved surface extends deeper into said outer surface of said female sleeve piece than the first grooved surface. 2. The detachable coupling of claim 1, wherein said transverse member is of a configuration such that when seated within said first grooved surface, said transverse member does not substantially extend beyond the outer surface of the female piece.3. The detachable coupling of claim 1, wherein said U-shaped staple has a peripheral surface which includes at least one radially recessed surface portion to permit a predetermined amount of fluid flow thereby.4. The detachable coupling of claim 1, wherein said female sleeve piece includes a first end configured to receive said male piece and a second end configured to fixably connect to a flexible hose.5. The detachable coupling of claim 1, wherein said U-shaped staple has a generally D-shaped cross-section and has a radially recessed surface defined in a peripheral linear surface thereof.
