Abstract: A telescopic extender for extending an interchangeable socket of a socket wrench, more particularly, an extender which automatically, slidably and continuously adjusts its length by infinitely small increments for use during a ratcheting operation confined to an inaccessible space between two fixed walls. The extender includes a tubular member, a pair of axially extending slots defined by the wall of the tubular member, a shaft member having a first end slidably extending into the tubular member and a second end extending out of the tubular member provided for receiving the socket, the second end adapted to the receive a socket. The shaft member is further provided with at least one protruding member extending into each of the axially extending slots, which combination permits slidable retention of the shaft within the tubular member. The protruding member is a removable pin which is passed entirely through a bore in the shaft member and into the two slots.
