A plug gauge (1) includes a support and protection frame with a handle (2) that defines a longitudinal axis and houses a position transducer (25) and electronic devices for wirelessly transmitting electrical signals indicative of a dimension to be checked. The gauge also comprises a probe (6) including a mechanical armset (7) provided with at least one movable feeler (10), and a transmission mechanism with a stem (17) transmitting movements of the feeler to the position transducer housed in the handle. The probe is connected to the handle by means of a quick coupling mechanism (5) with deformable locking portions (52), the radial arrangement of which is controlled by a clamping element (60).
