Self-closing positive engagement clip

A self-closing clip member (10) includes a body (12) having first and second walls (26, 28). A clamp member (30) is integrally connected to the first wall (26) by a living hinge (32) allowing the clamp member (30) to rotate from an open position into a cavity (34) created between the first and second walls (26, 28) upon direct contact by a tube member, defining a clamp member locked position retaining the tube member. Multiple anti-slide features include a first tab (46) extending from a second wall portion first end. A second tab is oppositely positioned on the second wall. The first and second tabs (46, 48) define cavity end extents. The second tab (48) further extends from a shelf (50) providing a connection between the first wall (26) and an angled intermediate wall (52). A third tab (56) extends between and is integrally connected to both the intermediate (52) and first (26) walls. The tabs (46, 48, 56) define an anti-slide system preventing the clamp member (30) in the locked position from moving in a direction co-axial to the cavity (34).
