Devices and methods for releasably securing components of a device having a sliding sleeve arrangement to prevent premature actuation due to vibration. In a currently preferred embodiment, standard elastomeric O-rings are used as shear members. The O-ring shear members reside within spaces formed between two slidable sleeve members. The O-rings are sheared cross-sectionally to allow the sleeve members to move axially with respect to one another. An exemplary coiled tubing shear release joint is described that incorporates a shear disconnect assembly which uses elastomeric O-rings as shear members. Multiple O-ring seals can be used as shear members to increase the shear value of the device. The use of O-rings as shear members helps prevent premature sliding of sleeve components in response to high vibration. Because the O-rings are resilient, they absorb vibration and do not shear during vibration, the connection between the two sleeve components will not be released prematurely.
