Abstract

A spring lock device (10) to prevent axial and/or rotational motion of a shaft or rod member (12); the device comprises a locking element in the form of a coil spring (16) arranged in a casing (10), is loosely disposed around the shaft or the rod (12), to provide a locking action in a required position. A thrust member (18) operatively connected to a pressure actuated control device (19) acts on the arms (16A, 16B) of the coil spring (16) to grip the rod (12) preventing any sliding and/or rotational movement.
