A connector (12) such as a multi-coupler stabplate for coupling to or decoupling from another connector (14). The connector may have a secondary release mechanism (80) that allows a seized drive to be rotated to an unlocked position independent of the connector housing moving relative to a multi-coupler plate. Integrated stop features may be provided during such secondary release. The secondary release mechanism may be mounted to the housing (56) and retained with shear pins. Orientation pin(s) (62) may be provided that cooperate with a guide slot(s) (64) for oblique and axial movement of a locking mechanism (46) during coupling/decoupling. A housing shroud (76) may be provided for cooperating with the orientation pin(s) and indicating locked/unlocked states. A stop collar (70) and push-off flange (74) may be provided for facilitating coupling/decoupling. Guide bushings (44) may be provided for facilitating alignment during coupling. One or more additional features may be provided that improve the securing/releasing function(s) of the connector.
