The present invention provides a mechanism (11) for firmly connecting an attachment to a construction machine. Generally, the mechanism (11) comprises two pairs of opposite facing hooks for engaging the pins of an attachment. Preferably, two stationary, downwardly facing hooks (12, 14) project from a base (25), and two movable, upwardly facing hooks (13, 15) project from a joining member (30). A hydraulic cylinder (16) moves the hooks together to catch and surround the attachment pins. When the attachment has a pair of pins, one stationary and one movable hook surround each pin. When the attachment has three pins, one stationary and one movable hook surround the central attachment pin. The second stationary and movable hooks engage the outer attachment pins. |
