A protective sheath (10) for an elongate substrate such as bundle of wires, hoses or the like consists of a body (11) of resilient material provided with substantially circumferentially extending corrugations (12, 13) and a side wall longitudinally slit at (25) to allow for installation over the substrates. The sides of the slit are defined by edges (21, 22) of the corrugated body wall biased towards and abutting, slit-closing disposition. Fastening means (30) in the form of complementary strips of hook-and-loop fastening tape (14, 15) is applied to the abutting edges (21, 22) of the slit so that the hooks and loops interlock when the slit is closed. The hook-and- loop tape protects the fingers of the worker during opening of the slit for installation of the tubular article, and prevents relative movement of the slit edges caused by turning and twisting forces, thereby eliminating undesirable noise during use and the need for taping following installation.

L'invention concerne une gaine protectrice (10) destinée à un substrat allongé tel qu'un faisceau de câbles, des tuyaux ou analogues. Cette gaine consiste en un corps (11) en matériau élastique pourvu de cannelures sensiblement circonférentielles (12, 13) et d'une paroi latérale fendue sur sa longueur (25) de manière à permettre l'installation de la gaine sur les substrats. Les côtés de la fente sont définis par des bords (21, 22) de la paroi cannelée du corps poussés l'un vers l'autre et contigus pour permettre la fermeture de la fente. Un élément de fixation (30) sous la forme de bandes à fermeture auto-agrippante complémentaires (14, 15) est placé sur les bords contigus (21, 22) de la fente, de manière que les boucles et les crochets de la bande à fermeture auto-agrippante entrent en prise lorsque l'on ferme la fente. La bande à fermeture auto-agrippante protège les doigts du travailleur lors de l'ouverture de la fente en vue de l'installation de l'article tubulaire, et empêche tout mouvement relatif des bords de la fente provoqué par des efforts de rotation et de torsion, éliminant ainsi le bruit indésirable lors de l'utilisation, et évitant de devoir fermer l'installation avec un ruban.
