Claim 17:
18. A surgical fastening instrument comprising:
(a) a first half comprising a proximal pivot member, wherein the proximal pivot member has a non-circular transverse cross-section; and
(b) a second half configured to releasably couple with the first half and to pivot relative thereto about the proximal pivot member, wherein the second half comprises:
(i) an elongate member operable to deploy fasteners toward the first half and at least one proximal receptacle configured to pivotably receive the proximal pivot member of the first half, and
(ii) a locking member configured to translate between a distal locked state in which the locking member selectively captures the proximal pivot member and a proximal unlocked state in which the locking member selectively releases the proximal pivot member for coupling and separating the first and second halves, respectively,

wherein a portion of the proximal pivot member is configured to selectively frictionally engage at least one of a proximal surface of the at least one proximal receptacle or a distal surface of the locking member in response to rotation of the first half away from the second half about the proximal pivot member to an open state in which the first and second halves remain releasably coupled together.
