Abstract

L'invention concerne la fixation par surmoulage d'une embase sur un tube en matière glissante. On munit le tube, à l'endroit prévu pour le surmoulage, d'un épaississement externe en 2 de sa paroi Cet épaississement favorise l'accrochage de l'embase. Application aux tubes en polytétrolluoroéthylène des cathéters.The invention relates to the fixing by overmolding of a base on a tube of sliding material. The tube is provided, at the place provided for the overmolding, with an external 2 thickening of its wall. This thickening promotes the attachment of the base. Application to polytetrolluoroethylene tubes for catheters.
