ABSTRACT:
A flash accessory is disclosed being releasably attachable to a photographic camera. The accessory includes a housing having a unitary latching member with a finger-engageable portion at one end and a spring portion at the other end and at least one depending finger carrying at its distal end a latching formation. The spring portion engages a section of the housing so as to bias the finger in one direction. During mounting of the accessory to the camera, the latching finger engages the camera in a manner that overcomes the biasing force of the spring portion and moves the finger and member in the opposite direction. When the finger reaches a latchable condition, the spring portion causes the finger to tightly engage with a latching section formed on the camera. Release of the latching finger is initiated by manually displacing the finger-engageable portion in the opposite direction to overcome the biasing force provided by the spring portion.
