Abstract
To permit separation of a fire sensor element from a socket element, but prevent accidental, or unauthorized removal and separation, the socket element is formed with a movable catch engaging in an opening or recess in the sensor element, upon moving the sensor in engaged position with respect to the socket. The catch can be released from engaged position only by a removal tool pressing the catch out of engagement, the removal tool preferably being so constructed that it surrounds the sensor element to inhibit contact of the person handling the removal tool with the sensor element, and thus prevent contamination of the sensor element, or injury to the operator if the sensor element contains dangerous materials.
