ABSTRACT:
A holding device for attaching a strobe grip to a camera bracket which comprises a first retainer with an insertion hole in the center, a lock lever, a locking slit, a clamp lever, and a second retainer with a central through-hole, arranged in the order described. The lock lever is controlled lengthwise by a locking spring and axially by a compression spring which presses on the side of the clamp lever. Opposed faces on the clamp lever and the second retainer have the shape of an inclined cam so that the clamp lever can be moved against the compression spring toward the strobe grip when turning the clamp lever in tightening direction. The second retainer is engaged by a jack so as to hold the jack, which has a convex rubber member in engagement with an annular rubber member on the second retainer. The camera bracket is provided with a pin having a head in the center for engagement with the locking slit. The pin cooperates with the lock lever whose axial position is controlled by the compression spring and the clamp lever to engage or disengage the jack from the second retainer.
