CA 2283238

A tubular article (10) useful for bundling wire or cables or for creating a seal between two surfaces (28, 29), such as an oven (30) and an oven door (32), is provided with externally applied attachment clips (14). The clips are formed from separate pieces of wire, each of which is bent at an acute angle at its mid-point to form a head portion (16) and a pair of shoulders (19, 20) which fit into an aperture (27) on one of the surfaces to be sealed. The clip further includes crossed intermediate portions (21, 22) followed by ransversely extending base legs (23, 24). The base legs (23, 24) are passed through the wall of the tubular article (10) and clinched so that they extend back towards the crossed portions. Gaskets are disclosed comprised of yarn, such as glass fibre yarn, interbraided with stainless steel wire. The spacing between clips (14) may be varied to accommodate variations in aperture spacing and/or to provide tubular articles which are braided and are capable of varying in diameter at different locations along surfaces to which they are attached.

La présente invention concerne un article tubulaire (10) pourvu de pinces de fixation (14) extérieures, utile pour regrouper les fils métalliques ou câbles ou pour créer un scellement entre deux surfaces (28, 29), telles qu'un four (30) et une porte de four (32). Les pinces sont formées de pièces de fil métallique séparées, chacune étant pliée au milieu selon un angle aigu pour former une partie tête (16) et une paire d'épaulements (19, 20) qui s'insèrent dans une ouverture (27) sur une des surfaces devant être scellée. De plus, la pince comprend des parties intermédiaires croisées (21,22) suivies de segments formant une base (23, 24) et s'étendant transversalement. Ces segments (23, 24) sont passés à travers la paroi de l'article tubulaire (10) puis repliés de façon qu'ils soient ramenés vers l'arrière en direction des parties croisées. Cette invention décrit également des joints d'étanchéité comprenant un fil tel qu'un fil de fibre de verre tressé avec un câble en acier inoxydable. L'espacement entre les pinces (14) peut varier pour tenir compte des variations dans l'espacement d'ouverture et/ou pour constituer des articles tubulaires tressées capables de changer de diamètre à différents endroits le long des surfaces sur lesquelles ils sont fixés.
