Abstract
A rotary finishing tool, such as a buffing pad, utilizes a connector assembly for demountable attachment to a powered rotary backing plate. The finishing tool is attached to the front face of a backing disc and the rear face of the backing disc includes a first piece of the connector assembly, the second piece of which is carried by the backing plate. The first and second connector pieces include complementary driving surfaces and complementary locking surfaces which respectively interengage in response to linear movement bringing the two connector pieces together and relative radial movement between the locking surfaces which are preferably resiliently biased.
