Each of the slots subtends less than 360.degree.. Each of the slots have a first portion with a width which extends generally circumferentially of the cylindrical wall and a second portion which extends generally longitudinally of the cylindrical wall beyond the width of the first portion. Each of the first and second tubular members has a distal extremity and portions proximal of the distal extremity and means fastening together the distal extremities of the first and second tubular members while permitting other portions of the first and second tubular members to move with respect to each other during bending of the distal extremity.
