Abstract
Abstract There is disclosed herein a game racket having a frame formed from a single length of tubular framing shaped into an oval and having parallel extensions for the handle. The extensions are provided with connectors which space the extensions a fixed distance apart and provide interlocking means for securing the extensions to each other. Handgrip means in the form of two complementary sections encase distal end portions of the extensions and the connectors to provide a grip for the racket.
