A shape-memory alloy coupling system for connecting two or more members and selectively preventing premature locking. The coupling system includes a coupling device adapted for connection to a member and being at least partially formed of a shape-memory material. The coupling device has a first configuration that allows relative movement between the member and the coupling device, and a second configuration that limits relative movement between the member and the coupling device. A blocking element co-acts with the coupling device to selectively prevent the coupling device from assuming the second configuration.
