to its latched position. The pivot shoes (Bc,Bd) are connected together by bars (F3,F4)
Each pivot shoe (Bc, Bd) includes a cam member (Cc, Cd) which is rotated on pivoting
of the closure member (30) away from the channel (27a) and forces legs (B1,B2) of
the shoe (Bc,Bd) into engagement with side walls (27i,27ii) of the channel (27a) to
lock the pivot shoe (Bc,Bd) in position in the channel (27a). Each pivot shoe (Bc,Bd)
