Abstract: A tubing anchor assembly for seating and supporting coiled tubing in a tubing head, which includes as a first element, a slip assembly characterized by multiple slip segments inserted in the slip bowl of the tubing head and each provided with a bevelled top face and a vertically oriented dove tail slot. As a second element, slip retainer screws are radially threaded in the tubing head body at spaced intervals, each of the slip retainer screws provided with a frustro conical tip having a bevelled tip base, and each tip extending into the slip bowl of the tubing head and engaging a dove tail slot in one of the slip segments. The slip segments are maintained in open configuration inside the upper portion of the slip bowl when the tips of the slip retainer screws are in engagement with the dove tail slots and when the slip retainer screws are threadably retracted in the tubing head body.
