Abstract
Abstract A wrap-around sleeve for enclosing a cable join has opposing edge portions which can be held together to maintain the sleeve in a wrapped configuration. An adhesive coated flap lies under the edge portions to form a seal between them. When the enclosure is to be re-entered, a central part of the sleeve is cut away, and a new sleeve installed to bridge the butts of the old sleeve which are allowed to remain on the cable. In order to avoid leak paths between the edge portions of the remaining butts, adhesive from the flap is allowed to flow between the edge portions on original installation. This is achieved by providing localized separation between the original edge portions.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
105 words
A closure assembly comprising: a wrap-around sleeve having edge portions which can abut to hold the sleeve in a wrapped configuration; a sealing member which can underlie and bridge the edge portions when abutting, and having a heat softenable sealant on a major surface facing the edge portions; urging means inside said sleeve bearing on said sealing member for applying pressure on the sealant when heat softened; and means which provides localized separation which extends from the inside of the sleeve through the abutting edge portions and extends between the abutting edge portions allowing only localized flow between them of said sealant when heat softened.
Claim 2
Dependent Claim
105 words
A closure assembly comprising: a wrap-around sleeve having edge portions which can abut to hold the sleeve in a wrapped configuration; a sealing member which can underlie and bridge the edge portions when abutting, and having a heat softenable sealant on a major surface facing the edge portions; urging means inside said sleeve bearing on said sealing member for applying pressure on the sealant when heat softened; and means which provides localized separation which extends from the inside of the sleeve through the abutting edge portions and extends between the abutting edge portions allowing only localized flow between them of said sealant when heat softened.
Claim 3
Dependent Claim
47 words
An assembly according to claim 1, in which the means which provides separation between the edge portions is at least one groove in an edge portion which defines a hole between the edge portions when abutting, the hole being substantially radial with respect to the wrapped sleeve.
