Abstract
The unit has a mounting sleeve connected to an earthed conductor pipe for fitting into a support, and is particularly for use in a thermo-electric fire detector system. The sleeve (2) has a screw thread (3) over part of its length, and has annular grooves (5) at intervals along the remaining smooth part (4). The fixing devices (7, 10, 14, 21, 22) are sleeve-shaped components, working in conjunction with the smooth or screwed parts and the support. The diameter of the screwed part can be less than that of the smooth part. The component working in conjunction with the screwed part can be in the form of a roughened sleeve (7) with an internal screw thread.
