Abstract

The locking system comprises a locking device (1) which consists of two side parts (2-3 and 5) made of metal and an intermediate part (4) made of an elastic, easily deformable material. The locking device side part (5) functions as a locking latch and when fitted it bridges the distance between a locking surface (17) on a replaceable wear part (13) on e.g. earth moving machine tools and another locking surface (18) in its holder (14). A special mandrel, for removing the locking device (1), is provided and is pointed at one end and can be rotated in the opening (23). Both the periphery of the mandrel and the neighbouring surface (6) of the locking device are equipped with a friction increasing pattern. By entering the mandrel completely into the opening (23) the locking device (5) is pressed away from the locking position (18) and by rotating the mandrel the locking device can be fed out of the locking position.
