Abstract

A hose and quick connect coupling assembly comprising a receiving hose, an insertion hose, a pair of quick connect coupling halves each coupling half being identical to the other, and a securing clasp. The securing clasp releasably secures the coupling halves around the receiving hose, thereby forming a releasable coupling as the insertion hose in inserted into the receiving hose. The insertion hose may be removed by depressing the coupling halves together, causing the top portions thereof to pivot away from the insertion hose. The securing clasp may also be removed from the hose coupling, thereby removing the coupling halves from the receiving hose.

Claims

1. A quick connect hose coupling for attaching an insertion hose to a receiving hose, the hose coupling comprising:

2. The quick connect hose coupling according to claim 1, further comprising:

3. The quick connect hose coupling according to claim 2, further comprising:

4. The quick connect hose coupling according to claim 3, further comprising:

5. A hose and quick connect coupling assembly comprising a first receiving hose having a receiving end, an insertion hose having an inserting end, a pair of quick connect coupling halves each coupling half being identical to the other and having an attachment end, a receiving end, an inner surface, and an outer surface, an adapter attached to the receiving end of the receiving hose, the adapter having a hose attachment section, a top section having a distal end, and a waist section, the waist section being of smaller diameter than both the hose attachment section and the top section, and the top section containing opposing slots cut into the top section towards the distal end thereof, creating an annular rim between the slots and the distal end of the top section, and a securing clasp, such that the securing clasp releasably secures the first and second coupling halves about the receiving hose, thereby releasably securing the receiving hose to the insertion hose as the insertion hose in inserted into to the receiving hose, wherein the securing clasp is an elliptical metal band having resilient spring-metal qualities, the securing clasp having an opening at one end to facilitate securing the clasp around the coupling halves.

6. The quick connect hose coupling assembly according to claim 5, wherein the inserting end of the insertion hose is adapted to have an annular locking groove bordered on the side closer to the inserting end by an annular step, and on the other side by an annular stop, both the annular step and the annular stop being of a larger diameter than the annular locking groove.

7. The quick connect hose coupling assembly according to claim 6, further comprising a pair of opposing, diagonally aligned tracks along the outer surface of each coupling half, for receiving the securing clasp.

8. The quick connect hose coupling assembly according to claim 7, further comprising:

9. The quick connect hose coupling assembly according to claim 8, wherein as the insertion hose is inserted into the adapter of the receiving hose, the locking tabs of the coupling halves engage the annular locking groove of the insertion hose, thereby securing the insertion hose to the receiving hose.

10. The quick connect hose coupling assembly according to claim 9, further comprising:
