ABSTRACT:
The present invention relates to a heating device having at least a first heating element102for heating at least one protective sleeve105, 602arranged around at least a first uncoated optical fiber section501, 603. Said sleeve105, 602being arranged to shrink when exposed to heat to form a protecting member tightly enclosing said uncoated optical fiber section501, 603. The at least first heating element is flexible, and arranged to take at least a first open state and a second substantially closed state. Said first open state is suitable for inserting and removing said protecting sleeve and fiber into and out off said heating device. Said heating element, in said second state, substantially surrounds said sleeve to form an enclosure around said sleeve, so that said heating element radiates heat around substantially the complete circumference of said sleeve.
