Abstract

A closure for cable connection capable of positively maintaining fastening between joint edges of a sleeve, exhibiting increased safety and airtightness, and substantially improving workability in assembling thereof. A sleeve is formed so as to be split into two parts in an axial direction thereof. The two parts of the sleeve are connected on one side thereof to each other by means of hinge sections and formed on the other side thereof with joint edges. One of the joint edges is mounted thereon with fasteners each provided with a holding hole and the other joint edge is provided with holding projections each releasably engaged with a corresponding one of the holding holes. Each fastener and the sleeve are provided with a holding hole and an additional holding projection for locking the fastener to the sleeve in a manner to be opposite to each other, respectively.
