ABSTRACT:
What is disclosed is an improvement in a tubing clamping apparatus in which a hose carrying a fluid is to be connected in fluid tight relationship with an appliance; such as, a welding torch, pressure regulator or the like; the improvement being characterized by a hose barb sealingly connected at one end with the appliance and having an outwardly extending free end having an enlarged inverted frusto-conical section thereon for sealingly receiving the hose inserted thereover, a hose inserted over the hose barb, a thermoplastic clamping means disposed about the hose and encompassing the hose between the clamping means and the hose barb to hold the hose sealingly and frictionally in place, and a retainer means for retaining the clamping means in clamping relationship with the hose and the hose barb; the retaining means being forced toward the appliance so as to apply a radially inwardly biasing force on the clamping means.
