ABSTRACT:
The invention disclosed is a means of fastening flexible elastic tubing, such as silicone rubber, to a rigid connector. The invention allows for a liquid and gas tight, secure connection without the use of any bonding materials between the tube and the connector and without any external ribbing, threading, texturing, barbing, etc. of any kind on the connector and without any external clamping mechanism used to keep the tubing firmly attached to the rigid connector.
The invention allows for the rigid connector portion of a component, such as a wound drainage surgical needle, to have a very smooth cylindrical surface. The use of a smooth surface with no other adhering mechanism to assist in making a secure connection that will not easily pull off is contrary to what is taught in the art.
