ABSTRACT:
A tool holder has a socket to receive the shank of a tool, a transverse bore breaking into the socket, and a tool retaining device for insertion in the transverse bore comprising a rigid retaining pin bonded to a resilient member which urges the retaining member sideways so that part of the retaining pin projects into the socket to engage the shank of a tool inserted therein. An elongate element is bonded to the resilient element and includes, at opposite ends thereof, stop members which overlie surfaces of the tool holder surrounding the ends of the bore, and thereby prevent longitudinal movement of the retaining device in the transverse bore. The stop members may be moved, by deformation of the resilient member, to a release position where they lie within the cross-section of the transverse bore, so that the retaining device may be inserted into, or withdrawn from, the bore.
