A retaining device, a retaining system between a female part and a male part, and a female part and male part to assure retention between a wear element or tooth and an adaptor element or tooth bar used in excavators and the like. The female part, which can be a wear element or tooth, or an adaptor element or tooth bar, has, auto-fixed thereto, a retaining device which participates in the coupling with a pin of the female part with a male part, and prevents the pin from coming out of its blocking position, maintaining the fixing between the two parts, i.e., male part and female part. The coupling between both parts is detachable, allows removing the pin from the coupling and replacing the female part or male part together with the retaining device. The retaining device is formed by one or more attached tightening elements.

Retention device for male and female components in excavator machines

The invention relates to a retaining device, a retaining system between a female part and a male part, and a female part and male part to assure the retention between a wear element or tooth and an adaptor element or tooth bar used in excavators and the like. The female part, which can be a wear element or tooth, or an adaptor element or tooth bar, comprises, auto-fixed thereto, a retaining device which participates in the coupling with a pin of the female part with a male part, and prevents the pin from coming out of its blocking position, maintaining the fixing between the two parts, i.e., male part and female part. The coupling between both parts is detachable, allows removing the pin from the coupling and replacing the female part or male part together with the retaining device. Said retaining device is formed by one or more attached tightening elements

A coupling system for coupling a wear element to an adapter for excavators and similar machinery and the components thereof. The coupling system is formed by a wear element, preferably a tooth though possibly a bucket protection element, a tooth bar or adaptor element and a securing system for securing the two elements, formed mainly by a pin. In addition, the securing system can include a retaining element with resilient properties, associated with the pin.
