Abstract
Abstract A one-piece connector has a stepped bore, a first end to accommodate an outlet pipe of an outlet tap of a urine drainage leg bag, and a second end to accomodate a nozzle on an inlet pipe of an overnight drainage bag. The second end includes a hand-grippable tab with an enlarged free end. The connector is removed from the nozzle by pulling the tab in a direction towards the leg bag. This pulling action on the tab reduces substantially the tension needed to separate the connector from the nozzle.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
121 words
A device for connecting a nozzle to a tube, said device comprising a cylindrical molded elastomeric connector tube having two ends, each one of said ends being adapted to accommodate either the nozzle or an end of the tube, an attachment area on the circumference of the exterior cylindrical surface of the connector tube at a terminal zone of one of said tube ends, and a hand-gripped elongate appendage protruding from said attachment area toward the other of said tube ends at an acute angle to the longitudinal axis of the connector tube, said elongate appendage comprising means for reducing the tension needed to separate the connector from the nozzle or tube when the appendage is pulled towards said other end.
Claim 2
Independent Claim
121 words
A device for connecting a nozzle to a tube, said device comprising a cylindrical molded elastomeric connector tube having two ends, each one of said ends being adapted to accommodate either the nozzle or an end of the tube, an attachment area on the circumference of the exterior cylindrical surface of the connector tube at a terminal zone of one of said tube ends, and a hand-gripped elongate appendage protruding from said attachment area toward the other of said tube ends at an acute angle to the longitudinal axis of the connector tube, said elongate appendage comprising means for reducing the tension needed to separate the connector from the nozzle or tube when the appendage is pulled towards said other end.
Claim 3
Dependent Claim
19 words
A device as claimed in claim 1 in which the appendage has an enlarged free end to assist gripping.
Claim 4
Dependent Claim
22 words
A device as claimed in claim 1 in which the free end of the appendage includes a ring-shaped member to assist gripping.
Claim 5
Dependent Claim
25 words
A device as claimed in claim 1 in which the appendage is contiguous with the said one end of the tube at the terminal zone.
Claim 6
Dependent Claim

A device as claimed in claim 1 in which the appendage is essentially planar.
Claim 7
Dependent Claim
25 words
A device as claimed in claim 5 in which the appendage protrudes at an angle of approximately 15° to the longitudinal axis of the tube.
Claim 8
Dependent Claim
41 words
A device as claimed in claim 1 further including a second hand-grippable appendage protruding from an attachment area on the circumference of the exterior cylindrical surface of the connector tube within a terminal zone of the other of said tube end.
