<p>A method of making a fluid tight coupling to a length of corrugated tubing (1) is described comprising the steps of providing a tubular coupling member (2) which fits over the corrugated tubing (1), and causing at least two rolling action circumferential grooves (10,11) to be provided in the coupling member (2) to cause it to be radially compressed into contact with the corrugated tubing (1). A hand tool is also described for forming the circumferential grooves (10,11) in the coupling member (2).</p> |
