A locking clamp is provided that is used for securing at least one tube. The locking clamp has a first and second end axially opposed end pieces and a plurality of locking members extending between the first and second end pieces. Living hinges connect the first and second end pieces to the locking members and allow selective movement of the locking members between an unlocked position and a locked position. In the locked position, the locking members can extend in overlying partially coextensive relation to each other, and the one set of locking members can be defined in a substantially axially opposed, coplanar parallel relationship to the second set of locking members. The clamp may be used during high pressure applications to secure one tube in relationship to another tube.
