摘要

Fixing device for sealingly fastening perforated articles, including first and second elements that constitute an interconnection device that serves, when said elements are assembled, to hold together said elements, each element being provided with a fixing surface that cooperates when said elements are assembled and interconnected by means of said interconnection device, to be coupled and fixed against the opposite surfaces of said articles, one of said elements being provided with a stem of reduced diameter extending from its surface of fixing, and whose dimensions are such that it penetrates into said holes formed in said articles, and being provided with a tubular end made of deformable material, said stem having a length greater than the length of said holes formed in said articles, said surface being fixation on the other of two elements a rim forming means which acts when said elements are assembled to radially deform said tubular end and produce a peripherally continuous rim that extends radially and which engages with the adjacent surface of said article around said orifice and held in a sealing position with it by said fixing surface of said other element, said other element serving to produce a seal with the adjacent surface of said articles around said orifices and in cooperation with said stem thereof and with said edging to create a complete hermetic closure of said holes when said elements are assembled.
