A separable putter golf club includes an upper shaft portion with a grip and a lower shaft portion with a club head, wherein the upper and lower shaft portions can be quickly connected and disconnected, while allowing a large amount of force to be transferred there through. The upper and lower shaft portions may be connected by a first and second connector portions, that may be engaged and rotated relative to each other. The first connector portion may include a first locking member having a plurality of outwardly protruding lugs and a guide rod, while the second connector portion may include a second locking member having a cavity and a bore. The bore is adapted to receive the guide rod, and the cavity is adapted to receive the outwardly protruding lugs. During connection, the user engages the first locking member with the second locking member, inserts the lugs into the cavity, and rotates the first and second connector portions relative to each other thereby causing the lugs to fixedly engage the cavity, which causes the upper and lower shaft portions of the golf club to be connected together.
