Claim:
A device to attach an elongated member to a bone in a patient, the device comprising: a receiver with a pair of spaced-apart arms that form a channel sized to receive the elongated member and a groove on an inner surface of at least one of the spaced-apart arms; a shaft operatively connected to the receiver and configured to attach to the bone; and a securing mechanism to attach to the receiver and capture the elongated member in the channel, the securing mechanism including a first member and a second member with the first member including a non-threaded exterior and being configured to engage with the groove to attach the securing mechanism to the receiver and including a bore that extends from a first end to a second end, the second member sized to fit within the bore and including a non-threaded exterior with a compressible extension; the second member including first and second ends and a size and shape to axially move along the bore with non-rotational movement from a first axial position with the extension positioned in the bore in a compressed orientation and including a first width and a second axial position in closer proximity to the shaft with the extension including a second width greater than the first width; the first member including a second compressible extension that extends outward from the non-threaded exterior and is movable between a compressed position and an expanded position with the expanded position configured to extend into the groove to attach the securing mechanism to the receiver; the second member being in closer proximity to the channel when the extension of the second member is at the second width.
