ABSTRACT:
A shrinkable protection element for covering filiform items, such as a joint between electrical cables. The element comprises a first (2) and second (3) sleeve, the second sleeve being coaxially superimposed upon the first one. Both sleeves are elastically expandable in a radial direction, i.e. shrinkable. The first sleeve is made up of a compound of cross-linked polymeric material including a peroxide curable hydrocarbon terpolyme of ethylene, propylene and a non conjugated dilene EPDM material, while the second sleeve is made of sulfur-cured EPDM material. As a result, the shrinking speed of the second sleeve (3) is higher than that of the first sleeve (2), especially at temperatures between 0.degree. C. and 40.degree. C. The cables may thereby be used about 30 minutes after the installation of the protection element thereon.
