Abstract
Abstract A catch for mounting on a swingable door including a support with a slidable bolt mounted within a chamber for movement between projected and retracted positions and urged toward the projected position by a spring. Two prongs formed integrally with and resiliently hinged to the bolt snap into a pair of elongated recesses in the chamber walls to prevent the bolt from sliding past its projected position. Flanges extending from the walls and into the chamber fit in corresponding grooves formed integrally in the bolt to guide the latter as it moves between its projected and retracted positions.
