<p>A cable sleeve outlet for splice cases comprising a cylindrical member, having an outer wall in which re-entrant portions are formed, each re-entrant portion constituting a cablereceiving channel and having a longitudinal opening to the exterior. One end of this cylindrical member is closed for containment of pressure. The re-entrant nature of the longitudinal openings allows an excess pressure to be maintained within the sleeve outlets without the bond between the channels and the cables therein being put into peel. A fastener is insertable into the open end of the cylindrical member. The fastener is so formed that in use it bears on an inner surface of, and thus provides a substantially rigid internal support for, at least part of the longitudinal outside wall of the cylindrical member in addition to the part thereof involved in the said bridging closure. The fastener is preferably in the form of two . half-shells with slots which engage the re-entrant portions to hold the openings closed. Sealant material such as hot-melt adhesive is preferably provided on the cable-contacting surfaces of the re-entrant portions and on the fastener. The cylindrical member may be closed at one end to effect a seal, especially for retaining pressure when used in pressurized splice cases.</p> |
