Abstract
A flexible tubular assembly having an outer flexible tube through which extends an inner flexible tube which is connected to a tubular element having an elbow-shaped locking piece. The outer flexible tube is joined to the tubular element and the inner flexible tube extends through a cylindrical section of the tubular element to the exterior of the element thereby exposing the end portion of the inner flexible tubing. The spout area of the elbow-shaped locking piece is inserted into the inner flexible tubing and thereby distends the tubing against the sides of an internal tubing and thereby distends the tubing against the sides of an internal tubular stub within the tubular element and locking the tubing in place. Outwardly extending ears on the elbow engage inwardly extending slots on the tubular element thereby holding the elbow in place. The device is specifically useful in anaethestic devices insuring the safety of a patient.
