A spring-biased latch is disclosed for removably attaching a first component, such as a seat, to an elongate member, such as the tubular frame of a wheelchair. The spring-biased latch comprises a body portion having a top and a pair of leg members that are adapted to removably receive an elongate member, a catch arm pivotally attached to the top of the body portion, and a release lever pivotally attached to the top of the body portion. The catch arm and release lever are configurable in a first position where the inboard end of the release lever abuts the inboard end of the catch arm such that the catch arm braces a portion of the wheelchair seat between the outboard end of the catch arm and the tubular frame of the wheelchair. The catch arm and release lever are also configurable in a second position where application of force to the outboard end of the release lever pivots the inboard end of the release lever away from the inboard end of the catch arm such that the catch arm pivots away from the wheelchair seat so that the catch arm does not brace a portion of the wheelchair seat between the outboard end of the catch arm and the tubular frame of the wheelchair. To re-secure the wheelchair seat to the tubular frame of the wheelchair, application of force to the outboard end of the catch arm pivots the catch arm and release lever so that the inboard end of the release lever abuts the inboard end of the catch arm and the outboard end of the catch arm braces a portion of the wheelchair seat against the tubular frame of the wheelchair.
