a cylinder tube having a closed end and an opposite open end, the opposite open end defining a first annular groove on a sidewall thereof and a slot defined through the sidewall and a portion of the first annular groove;

a piston rod having a piston mounted thereto and positioned within the cylinder tube for axial back and forth motion during operation of the hydraulic cylinder;

a gland located in the open end of the cylinder tube to seal the open end of the cylinder tube and allow the piston rod to move in a back and forth motion therethrough, the gland defining a second annular groove thereon and located so as to substantially overly the first annular groove and the slot, and

an elongate and flexible key inserted through the slot and positioned within the first and second annular grooves to rotatably attach the gland to the tube and maintain a desired relative position of the gland relative to the tube by maintaining the relative longitudinal positions of the gland and the cylinder tube while maintaining the relative rotary positions of the gland and the tube in the absence of a turning force below a predetermined level but enabling relative rotary motion when a turning force above the predetermined level is applied so as to permit the gland to be rotated relative to the cylinder tube, wherein the second annular groove includes a key aperture defined thereon and the key includes a first end configured to substantially engage the key aperture to facilitate installation of the key, and wherein the key includes a second wedge shaped end positioned adjacent the slot so as to taper away from the slot at an angle of from about 10 to about 20 degrees and provide an engagement surface for engaging a removal instrument to facilitate removal of the key upwardly and out of the slot for disassembly of the hydraulic cylinder.
