Abstract: There is disclosed a method of connecting tubes using a connector which comprises a body 41, through which is positioned a screw 43 having a head 44 and a threaded stem 45. A resiliently deformable member 413 is positioned on the threaded stem and a washer 46 is positioned on the threaded stem 45 the opposite side of the resiliently deformable member 413 from the body 41. A second washer 412 is positioned between the resiliently deformable member 413 and the body 41.
