A device (10) for restraining a guide wire (12) includes a base (16) having a recessed formation (30) configured to receive a portion of the guide wire, and a flexible lid (14) configured to fit on the base. The lid has a main sheet portion (44) covering the portion of the guide wire and a plurality of fingers (48) separated by gaps (49) and extending downwardly from a peripheral edge (46) of the main sheet portion to surround the base. Sandwiched between the lid and base, the guide wire extends through gaps between the finger members. Constructed of sheet material, the lid is flexibly movable between a closed configuration wherein the fingers are flexed inwardly engaging the base, and an open configuration wherein the fingers are flexed outwardly releasing the base. Alternatively, a clamping device (100) for restraining a guide wire (101) includes top and bottom clamp members (104, 102) and a pivot connection (106), wherein the top clamp member has a handle end (130) and a securing end (124) and wherein the pivot connection enables the top clamp member to pivot between a closed position restraining the guide wire and an open position releasing the guide wire.
