Patent ID: 8038181

Claim:
A fluid-conducting tube joint structure comprising: a fluid-conducting tube for conducting a fluid; a component for accommodating said fluid-conducting tube to receive the fluid and conduct the fluid away from said fluid-conducting tube; a collar formed on said fluid-conducting tube so as to project radially outwardly therefrom; a holder for clamping said collar axially against said component; said holder being a member having a body portion and having a bore formed in said body portion to accommodate a fastener for securing said holder to said component; said holder having two arms extending from said body portion laterally of said bore to define a U-shaped receptacle for receiving said fluid-conducting tube therein; said two arms extending from said body a predetermined length dimensioned to permit said arms to extend around more than half of the periphery of said fluid-conducting tube and grasp said fluid-conducting tube therebetween when said arms are plastically deformed; and, said U-shaped receptacle having a relief region in each of said arms wherein a reduction of material is realized so as to permit material of said arms to flow into said relief regions during the plastic deformation thereof thereby substantially preventing the cross section of said arms to thicken as a consequence of the material flow.
