A restrictor (32, 117a, 117b) within the storage housing reduces the inner diameter of the elongated flexible tube. A storage housing (14,114) with an open end (116) has an elongated flexible tube (28.128) disposed therein to receive the elongated flexible laser optical fiber so as to pre vent laser light from escaping the storage housing An elongated flexible tube, preferably constructed of silicone rubber is disposed within the storage housing to receive the elongated flexible laser optical fiber so as to prevent laser light from escaping the storage housing.
