An apparatus comprises a structure comprising a top, a bottom, a sidewall, a central hole extending from the top to the bottom, a void in a section of the sidewall, and a curved cavity disposed in the top. The central hole is configured to accept a shaft of a golf club. The void is configured to enable a length of the shaft to pass through the sidewall into the central hole. A compressible material is joined to a wall of the central hole to contact the shaft. A clasp is joined to the structure. The clasp is operable to rotate about the sidewall to close the void and retain the shaft within the central hole. A spring mechanism is disposed in the curved cavity and is joined to the structure and the clasp. The spring mechanism is configured to be operable to urge the clasp to close the void.
