The piezoelectric element of an engine knock sensor is held between upper and lower ring-shaped bases by two identical clips that extend through the piezoelectric element and engage each base. Each clip has a ring-shaped flange engaging a groove circumscribing the inner wall of one of the bases, with the flanges of the clips engaging opposite bases. Also, each clip has three legs that engage a groove in the opposite base. Each clip leg is disposed between two legs of the other clip.
