Abstract: A device for attaching a splice protector to a splice provided between two conductors includes a base; a receiver mounted on the base for receiving the splice protector in an open state thereof; two backup members situated at each end of the receiver for supporting the two conductors while the splice extends between the splice protector positioned in the receiver. The backup members are movable in a direction perpendicular to their conductor-supporting faces. Pressing jaws, which are mounted on at least one of the backup members, are disposed bilaterally of the receiver. At least one of the pressing jaws is pivotally attached to the backup member for a pivotal motion towards and away from the other pressing jaw.
