(57) An anchor grip for use in tensioning an elongate element for a prestressed concrete
structure comprises an elongate barrel (1) open at both ends (2,3), containing a wedge
gripping device (W), a taper spring (7) being biased at one end against the head (H)
of the device (W) and at the other end against an inside wall (8) of the barrel. After
a connection has been made within the barrel (1) (Figure 2), the head (H) of the device
(W) is visible from one end (3) of the barrel (1) for an operator to see that a proper
connection has been made.
