A structure comprising two interconnected metal tubes used for supplying oil or air. The first tube inserted in the second tube has a tubular wall at its one end and an outwardly swelling circumferential wall formed inside the tubular wall. The second tube has plural slots arranged circumferentially. A seal member is sandwiched between both tubes. A binding band is wound around the slots to compress the portion having the slots, for fastening the tubes together.

A structure comprising: a first tube having a substantially cylindrical portion generally adjacent one axial end, an outwardly extending circumferential stopper wall spaced from said end and an inwardly directed circumferential groove intermediate said stopper wall and said cylindrical portion; a second tube slidably disposed over the end portion of said first tube, said second tube having an axial end in abutting relationship with the stopper wall of said first tube, a plurality of spaced apart slits formed in said second tube and defining a circumferentially array of slits thereabout, the array of slits in said second tube being aligned with the inwardly directed groove of said first tube, portions of said second tube intermediate the slits therein being deformed inwardly and engaging the inwardly directed groove of said first tube; a generally annular seal disposed intermediate the second tube and the cylindrical portion of the first tube; and a circumferentially extending fastening means engaging the inwardly deformed portion of said second tube, whereby the slits in said second tube enable the fastening means to deform the second tube inwardly into the groove of said first tube for securely fastening said first and second tubes together.
