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.

A support for fitting a shrinkable sleeve onto an object inside the support and the sleeve 11 mounted on it includes at least two tubular parts removed in turn from under the sleeve. It further includes means for temporarily immobilizing the last part to be removed from under the sleeve during removal of the other tubular part.
