A resilient retainer is disclosed for a rocker arm coupling joining a valve assembly to a rocker arm assembly in an internal combustion engine. The rocker arm coupling comprises a first coupling member having a socket for receiving a ball extending from a second coupling member. The resilient retainer consists of unitary polymeric material comprising a resilient mounting portion and a resilient restricting portion. The resilient mounting portion is engageable with a recess delineated within the first coupling member for resiliently securing the resilient retainer. The resilient restricting portion permits insertion of the ball into the socket upon deformation of the resilient restricting portion with the resilient restricting portion inhibiting removal of the ball from the socket.
