ABSTRACT:
The latching device includes a tongue unit engageable with a clasping unit having a pair of divergable leaf members. The leaf members are held in superposed relationship by a clip member that extends from one leaf member to the other. An elastomeric or spring washer disposed on the clip member helps maintain the tongue unit and clasping unit in locking engagement. The locking engagement of the tongue unit and clasping unit is accomplished by establishing interference between a catch surface on one of the units and an abutment surface on the other unit. Release of the latching device is obtained when the leaf members of the latching unit are diverged against the influence of the elastomeric or spring washer to bring the abutment surface and the catch surface out of interference with each other thereby permitting withdrawal of the tongue unit from the clasping unit.
