Abstract: A mounting device for an elongate member, comprising: an elongate housing having an elongate axis; an internal passageway passing through the elongate housing parallel to the elongate axis; an elongate sleeve located within the internal passageway and being configured for longitudinal movement along the passageway; a plurality of ball-receiving recesses in the wall of the internal passageway, each recess having a ball-guiding surface inclined to the longitudinal axis; a plurality of apertures in the sleeve; a ball located in each of the ball-receiving recesses and engaged with a respective aperture in the sleeve, the balls and the apertures being configured to allow the balls to project partially through the apertures but to prevent balls from passing through; biasing means configured to bias the sleeve in a direction to urge the balls to project radially inwardly through their respective apertures in the sleeve and into the internal passageway.
