A disposable rupturable shipping and installation strap holding in a retracted position the output member of a linear actuator such as a pre-filled pre-bled hydraulic actuator. The strap has a retaining member fitted over the end of the actuator output member and a pair of symmetrically disposed strips or bands integrally formed with the retaining member and attached at their other end to a portion of the actuator housing. The strips or bands have portions of reduced strength which cause the strap to break and free the actuator output member upon first operation of the actuator. Preferably, the strap is molded of relatively thin flexible plastic.

1. A method of shipping and installing a hydraulic actuator for remotely operating a motor vehicle component, said hydraulic actuator forming part of an apparatus comprising a master cylinder, said hydraulic actuator and a conduit connecting said master cylinder and said hydraulic actuator, said hydraulic actuator having a housing and an output member movable relative to said housing from a first position to a second position, wherein said hydraulic actuator output member is connectable to an operating member of said motor vehicle component while in said first position, said method comprising restraining said hydraulic actuator output member in said first position by means of a strap having an end attached to said hydraulic actuator housing and another end attached to a portion of said hydraulic actuator output member, prefilling said apparatus with hydraulic fluid prior to shipment of said apparatus, shipping said apparatus with said strap maintaining said hydraulic actuator output member in said first position, and installing said apparatus on a motor vehicle while maintaining said hydraulic actuator output member in said first position by means of said strap, whereby said strap is adapted to maintain said hydraulic actuator output member in said first position during shipment of said apparatus and installation of said apparatus on a motor vehicle and to allow normal operation of said hydraulic actuator output member from said first position to said second position after installation of said apparatus on said motor vehicle. 2. The method of claim 1 wherein said hydraulic actuator output member is connectable to said motor vehicle clutch release mechanism. 3. The method of claim 1 wherein said hydraulic fluid in said actuator is at a pressure higher than atmospheric pressure. 4. The method of claim 3 wherein said hydraulic actuator output member is connectable to said motor vehicle clutch release mechanism.
