ABSTRACT:
The present invention is a coupling device for locking an excavation tooth onto an adaptor. The adaptor and tooth have a passage extending therethrough. The device includes a pin and retainer. The retainer is inserted into the adaptor. The pin includes a retainer seat for engaging the retainer. The retainer seat has a front wall perpendicular to the longitudinal axis of the passage and a back wall which slopes away from the front wall. As the pin is inserted into the passage, the retainer engages the pin until it enters the seat. The front wall then prevents the pin from being retracted from the passage. To remove the pin, force is applied to the driven end of the pin. The pin will continue through the passage while the retainer slides along the sloped back wall of the retainer seat. This arrangement allows for the easy insertion and removal of the pin with a relatively small amount of force.
