Latch and method of inserting a latch into an aperture

A method of locating a latch within an aperture in a wall, said latch comprising:

• a body having a forward end, a rearward end and a longitudinal axis, configured to be inserted into said aperture by said forward end of said body in a first direction parallel to said longitudinal axis, said body comprising:
• an inner part, and
• an annular outer housing surrounding at least part of said inner part and rotatable around said inner part;
• a plurality of latch fingers moveably attached to said annular outer housing, each of said plurality of latch fingers moveable between a closed position and an open position, such that in said open position a latch finger of said plurality of latch fingers prevents removal of said body from said aperture in a direction opposite to said first direction;
• and
• a guide attached to said body and configured to bias rotation of said annular outer housing, when said body is inserted into said aperture, to one of a set of at least one predetermined rotational positions, thereby also locating said plurality of latch fingers in a predetermined position;
• the method comprising steps of:
• inserting said body of said latch into said aperture, allowing said guide to rotate during insertion until said annular outer housing has reached said of said set of at least one predetermined rotational positions;
• and
• continuing insertion of said body until said plurality of latch fingers are in said open position, preventing removal of said body from said aperture.
