Abstract
A self choking cam lever action clamp is described for securing flexible plastic film over a supporting framework so that the film may be released if required. Esp. suitable for securing plastic covers over cold frame tunnels/cloches/greenhouses to resist wind forces but allow periodic exposure or access beneath the edges. The lever has an extended arm which can be used for remote control linkages.
