An installation mechanism for installing in an outer wall of a fluid flow passage a temperature sensor equipped with a thermal sensitive device and a cylindrical casing retaining the thermal sensitive device. The installation mechanism a mount base to be joined to the fluid flow passage, an attachment to be secured to the cylindrical casing, a hollow fastener to be placed around the cylindrical casing through a gap. The fastener is designed to be rotated to press a shoulder of the attachment into constant engagement of a tapered wall thereof with a seat of the mount base to fasten the cylindrical casing to the mount base. A shield disposed to close the gap to avoid the intrusion of foreign objects into between the cylindrical casing and the fastener, thereby ensuring the removal of the fastener to dismount the temperature sensor from the fluid flow passage.
