A latching mechanism removably attaches an accessory to an offroad vehicle without requiring tools. The latching mechanism includes a body, a shaft extending through the body, and a handle riding on a conical surface of the body for rotating the shaft relative to the body. An oblong head extends on a lower side of the body, rotatable by the handle and shaft to a position where the head extends under a shoulder of a mounting recess. A spring system biases the head axially, such that the head can be moved either upwardly or downwardly from a balanced elevation set by a nut tightenable on a bolt. The mounting recess has an upper portion shaped differently from a lower portion. The body includes a hooking portion which extends significantly above the top of the mounting recess.
