Abstract
Abstract A flexible tubing is disclosed herein having a length of preferably reinforced pliable material in which a circular resilient clamp of the self-tightening type is embedded at the opposite ends thereof. Each clamp comprises a length of wire stock formed in a circle encased by the tubing material so as to be integral therewith and having a pair of tangs outwardly projecting through the tubing material adjacent a cross-over of the opposite ends of the wire stock length. The circular wire stock is resiliently biased to form a clamping action about the tubing end which effects a sealing union between the tubing and a stationary conduit or duct insertably disposed in each end of the tubing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
115 words
A flexible conduit comprising, in combination: a length of hose composed of pliable material having open ends for insertably receiving stationary tubular ports; clamping means embedded in said hose pliable material adjacent said open ends; actuating means carried on said clamping means operable to secure and release hose material adjacent said clamping means with said tubular ports; said actuating meAns extending through said hose material exteriorly thereof in outwardly projecting relationship with respect to said hose material; and said clamping means being bonded to said hose material so that said hose material follows movement of said clamping means into and out of sealing relationship relative to said tubular ports in response to said actuating means.
Claim 2
Dependent Claim
115 words
A flexible conduit comprising, in combination: a length of hose composed of pliable material having open ends for insertably receiving stationary tubular ports; clamping means embedded in said hose pliable material adjacent said open ends; actuating means carried on said clamping means operable to secure and release hose material adjacent said clamping means with said tubular ports; said actuating meAns extending through said hose material exteriorly thereof in outwardly projecting relationship with respect to said hose material; and said clamping means being bonded to said hose material so that said hose material follows movement of said clamping means into and out of sealing relationship relative to said tubular ports in response to said actuating means.
Claim 3
Dependent Claim
37 words
The invention as defined in claim 1 wherein said hose material embedding said clamping means moves concentrically into sealing engagement and out of sealing engagement with said associated tubular port responsive to actuation of said clamping means.
Claim 4
Dependent Claim
38 words
The invention as defined in claim 2 wherein said clamping means includes a substantially circular band of spring wire stock normally biased to urge said hose material encasing said band into sealing relationship with said associated tubular port.
Claim 5
Dependent Claim
40 words
The invention as defined in claim 3 wherein said actuating means includes a pair of tangs integrally formed on the opposite ends of said wire stock that overlap to form said band and which outwardly project through said hose material.
Claim 6
Dependent Claim
57 words
The invention as defined in claim 1 wherein said clamping means further comprises a single substantially circular band molded in encasing relationship with said hose material so that said band is integrally formed with and surrounded by said hose material whereby movement of said band responsive to said actuating means is followed by said encasing hose material.
Claim 7
Dependent Claim
24 words
The invention as defined in claim 5 wherein the diameter of said hose open ends is larger than the diameter of said tubular ports.
Claim 8
Dependent Claim
54 words
The invention is defined in claim 6 wherein said clamping means band includes a pair of semi-circular arms formed as extensions of a bottom body portion wherein said arms are arranged to cross each other in a vertical plane intersecting said bottom body portion and to extend a substantial distance beyond said vertical plane.
Claim 9
Dependent Claim
39 words
The invention as defined in claim 7 wherein said actuating means includes a pair of tangs integrally formed with the opposite ends of said band arms that project outwardly from said encasing hose material parallel to said vertical plane.
