Abstract
A glow plug (1), includes a pressure sensor (90), suitable for measuring the internal pressure of a motor cylinder in which the plug (1) is housed, a body (10) to be secured to the motor and a finger (20) in which a heater electrode is housed. The sensor (90) is firmly secured to the body (10) by the upper face thereof and rests on the finger (20), so that the pressure exerted on the finger (20) presses the sensor against the body (10).
