Abstract
Abstract An adapter for connecting tubes is provided with an integrally formed clamp which may be manually manipulated from an open to a closed position to at least constrict a tube. The adapter further includes integral latch means, which is manually movable to a closed position by cam action, and which is releasably held in the closed position by the inherent elastic nature of the adapter body.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
236 words
An adapter for connecting first and second tubes comprising: an adapter body; first connecting means on said body for attachment to said first tube; second attachment means on said body for attachment to said second tube; manually movable compression means formed integrally with said body comprising a clamping member movable with respect to said body and having an arcuately shaped tube engaging portion, said compression means being movable under manual pressure from an open position to a closed position wherein one of said tubes is at least partially constricted; said body including an integrally formed support having an arcuately shaped tube engaging surface, said support being positioned opposite of said clamping member with respect to said one tube for cooperation with said clamping member when said compression means is positioned in said closed position to compress said one tube between said clamping member and said support, said arcuately shaped tube engaging surface being generally defined by a radius greater than a further radius generally defining said arcuately shaped tube engaging portion; said adapter further including latching means formed integrally with said body and formed by a portion of a wall defined by an opening through which said one tube extends, said wall being integrally formed with said support; said latching means being adapted to engage and coact with catch means formed integrally with said compression means to releasably retain said compression means in said closed position.
Claim 2
Dependent Claim
236 words
An adapter for connecting first and second tubes comprising: an adapter body; first connecting means on said body for attachment to said first tube; second attachment means on said body for attachment to said second tube; manually movable compression means formed integrally with said body comprising a clamping member movable with respect to said body and having an arcuately shaped tube engaging portion, said compression means being movable under manual pressure from an open position to a closed position wherein one of said tubes is at least partially constricted; said body including an integrally formed support having an arcuately shaped tube engaging surface, said support being positioned opposite of said clamping member with respect to said one tube for cooperation with said clamping member when said compression means is positioned in said closed position to compress said one tube between said clamping member and said support, said arcuately shaped tube engaging surface being generally defined by a radius greater than a further radius generally defining said arcuately shaped tube engaging portion; said adapter further including latching means formed integrally with said body and formed by a portion of a wall defined by an opening through which said one tube extends, said wall being integrally formed with said support; said latching means being adapted to engage and coact with catch means formed integrally with said compression means to releasably retain said compression means in said closed position.
Claim 3
Dependent Claim
61 words
An adapter as set forth in claim 1, wherein said radius which generally defines said arcuately shaped tube engaging surface corresponds to the outer radial dimension of said one tube, and said further radius generally defining said arcuately shaped tube engaging portion corresponds to the outer radial dimension of said one tube less twice the wall thickness of said one tube.
