A shape-memory alloy coupling system for connecting two or more members (12, 14) and selectively preventing premature locking. The coupling system includ es a coupling device (16) adapted for connection to at least one member (12, 14 ) and being at least partially formed of a shape-memory material. The coupling device (16) has a first configuration that allows relative movement between the member (12, 14) and the coupling device (16), and a second configuration that limits relative movement between the member (12, 14) and the coupling device (16). A blocking element (22) co-acts with the coupling device (16) t o selectively prevent the coupling device (16) from assuming the second configuration.
