    (54) Tamper-evident cap for a keg spear


    (57) A cap for a keg spear has internal teeth (13), which snap-engage over an annular projection on the spear. A tamper-evident ring (40) is provided on the cap skirt (12) and connected to the skirt by radial tags (41) having point attachment to the skirt. The ring obstructs access to the skirt for levering off the cap, so that any such attempt loosens the ring by breaking the tags to provide tamper evidence. The ring (40) is securely fixed to a tab (30,31) defined by a pair of lines of weakness extending axially in the skirt (12) and radially across the top (11) of the cap. The ring can be used as a handle to split the cap for removal in one piece.
