Cart wheel snap lock device

A snap lock device for securing a wheel assembly to an axle is provided. The snap lock device may be formed from one integral piece. The snap lock device may include a hubcap and a first and second clip extending from the hubcap. The first and second clips may include a spring, an engagement member, and an actuator. The spring may be directly coupled to the hubcap. The snap lock device may be installed in the wheel assembly by inserting the cap assembly in the wheel assembly such that the first and second clip are placed in two apertures of a wheel and the springs bias the engagement members toward a center of a bore defined in the wheel for receiving the axle. The snap lock device can allow for tool-less installation and removal of the axle.
