A quick release device for use with chain saws and which is adapted to quickly attach a bar and chain to the motor assembly of the chain saw. The quick release device comprises a body having an upper jaw and lower jaw. The jaws are adapted to engage notched ends of studs extending from a motor assembly and thereby clamp the bar and chain to the motor assembly. A rotatably threaded shaft cooperates with the body in a unique manner such that turning of the shaft in a manner which causes a clamping action actually biases the jaws away from one another. A head is located on the threaded shaft with a plurality of apertures so that one can readily engage an aperture with a tool thereby facilitating manipulation of the head.
