摘要： The invention relates to an extension joint for concrete piles of the type in which at least one pin in a first pile penetrates into a recess in a second pile. The end of the pin is provided with a shoulder and is locked in the second pile by means of a wedge having shanks each engaging one side of the pin. The wedge is locked in its driven-in position while being driven in by the bending of the shanks towards each other after they have passed the pin.
