Abstract
A manually-severable coupling device for coupling two tubes (12a, 12b), particularly useful in peritoneal dialysis, including a flexible plastic member having passageways (30) therethrough and formed with tubular end sections (31, 32) for receiving tubes (20, 24) to be coupled, an annular groove (33) formed intermediate the tubular end sections defining a flexible, weakened, annular web (33) capable of being severed by rotating one of the tubular end sections (31, 32) with respect to the other, and a finger gripping formation (34, 35) integrally formed in each tubular end section (31, 32) on opposite sides of the weakened annular web (33) grippable by a user to rotate the tubular end sections with respect to each other to sever them from each other along the weakened annular web (33).
