An access entry closure assembly for a drum of a concrete mixer or agitator, comprising a door member (90) and an insert (92), the door member comprising a plate (100) having mounted thereon a latching mechanism comprising a plurality of locking arms (110). Each locking arm is coupled, at a proximal end, to an actuating member (106) and extends substantially radially outwardly toward an edge of said plate (100). A distal end of each locking arm extends beyond the peripheral edge of said plate when in a locking position. The actuating member (106) is arranged and configured, when actuated, to cause linear movement of said locking arms (110) in a direction away from said edge of said plate so as to retract said distal ends thereof, each locking arm being retained in a retaining member (112) defining a slot through which a respective locking arm extends. Each retaining member (112) is provided on said plate and includes a biasing member (114) configured to engage a respective locking arm retained therein and bias said respective locking arm toward said plate.
