Response to Arguments Applicant's arguments filed 6/16/2026 have been fully considered but they are not persuasive. The applicant argues that Sacco’s throughbore will not slide along the line due to the ribs 41 which serve to grip the line and lack ant tapered guiding surface. This is found not persuasive as the claim was not claiming such function “slide along the line and guiding the line. However, the ribs 41 has a tapered and just before firmly attached to the line, the it can be position and move along the line to the right position. - the applicant is asked to further define the device structurally and/ or further define the function of the guide ..etc. Conclusion THIS ACTION IS MADE FINAL.
