Abstract: A tensioning device is provided for an endless drive device, having a housing, a spring-loadable tensioning piston in a piston bore of the housing, a transport locking device, and a device to adjust the working range of the tensioning piston with a retainer element on the housing having at least one spring arm and a retainer profile arranged in the forward section of the tensioning piston in the tensioning direction. The transport locking device comprises a transport groove in the tensioning piston, the spring arm of the retainer element being engageable into the transport groove, and an unlocking element, wherein the unlocking element has at least one ramp section potentially in functional contact with the spring arm. The ramp section exerts an unlocking force on the spring arm over a travel path of the unlocking element relative to the tensioning piston, forcing said spring arm out of the transport groove.
