Abstract: A tube clamp device including a sleeve like assembly comprising two identically semi-cylindrically shaped half sleeve members. Each of the half sleeve members is sized to the tube diameter being clamped, and has tongues thereon which extend beyond half the circumference of the tube being clamped to provide independent clamping or gripping of the tube by snap on action, the tongues of both half sleeves further providing interlock to prevent separation of half sleeves and separate longitudinal movement of the half sleeves along the axis of the tube. Circumferential shoulders at each end of the half sleeves provide a saddle seating for a loop clamp surrounding the half sleeves between the circumferential shoulders thereof.
