A mated connection between two sectional boom members of a crane comprises a first connector 70 on a first sectional boom member and a second connector 80 on a second sectional boom member. Each connector has first and second sets of extensions with apertures therethrough sized to receive a pin. A first pin (95) passes through the apertures of the first set of extensions (71-73a) of the first connector (70) and the first set of extensions (81-82a) of the second connector (80). A second pin (95) passes through the apertures of the second set of extensions (71-73b) of the first connector (70) and a second set of extensions (81, 82b) of the second connector (80). Each connector (70, 80) also comprises a compressive load bearing surface (78, 88) positioned between the first and second sets of extensions. The compressive load bearing surface (78) of the first connector (70) is in face-to-face relationship with the compressive load bearing surface (88) of the second connector (80).
