A curvilinear resilient pin for securing a tooth to the bucket of an excavating device includes a plurality of waves or undulations formed along its surface. The pin is inserted into a channel formed through a tooth support upon which the tooth is mounted as well as through apertures formed in the tooth. The waves or undulations contact and exert pressure upon the tooth and the tooth support so as to laterally restrain the pin within the channel.
