The spring means is mounted in a retractable cylinder and further comprises an air brake to counter the retraction of the spring in the event of sudden release of the grip by the user. The spring is within a retractably extensible cylinder. The cylinder has an air brake to counter retraction of the spring upon release of the hand grip.
