The present invention relates to a heating device having at least a first heating element 102 for heating at least one protective sleeve 105, 602 arranged around at least a first uncoated optical fiber section 501, 603. Said sleeve 105, 602 being arranged to shrink when exposed to heat to form a protecting member tightly enclosing said uncoated optical fiber section 501, 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.
