Enclosure assembly for use over elongate cylindrical objects such as electric cable splices

An assembly of an elastic sleeve with a supporting body in the bore of said sleeve for the application of said sleeve to a cylindrical body, said assembly comprising:

• a radially stretched sleeve of elastic material, the bore of said sleeve having an inner wall of a predetermined radius in its unstretched state and said sleeve having opposite ends;
• a support comprising two tubular bodies disposed within the bore of said sleeve, each of said bodies having a longitudinal axis, having an external surface around said axis of a radius greater than said predetermined radius and engaging said inner wall of said sleeve to cause radial stretching of said sleeve and having an internal surface around said axis of a radius smaller than the radius of said external surface, said bodies having opposite ends and being mounted co-axially with one end of a first one of said bodies abutting the end of the other second one of said bodies intermediate said ends of said sleeve and in mutual continuation;
• and
• a pair of pulling means, one of said pulling means being connected to said one end of first one of said bodies and extending within the internal surface of said first one of said bodies toward the opposite end of said first one of said bodies and the other of said pulling means being connected to said one end of said second one of said bodies and extending within the internal surface of said second one of said bodies toward the opposite end of said second one of said bodies.
