1. A latch for assembling a panel to a structure, said latch comprising:
a bracket, suitable for attachment to the panel, that includes a through-housing that extends along a first axis between first and second through-housing ends;
a sliding body, defining first and second sliding body ends, that is movable along the first axis inside the through-housing such that the first and second sliding body ends both move linearly relative to the through-housing; and
a hooking arm that extends along a second axis between a first hooking arm end that includes a hook and a second hooking arm end that is connected to the sliding body first end;
wherein
the hooking arm projects from the through-housing first end;
the hook of the hooking arm is configured to cooperate with a keeper fixed to the structure;
the hooking arm is movable relative to the sliding body between a first conformation where the second axis is inclined by a non-zero first angle (β) relative to the first axis and a second conformation where the second axis is parallel to the first axis;
the sliding body is linearly movable within the through-housing along the first axis between an unlocking position and a locking position;
in the unlocking position of the sliding body, the hooking arm is in the first conformation and said hooking arm is in a first axial position relative to the bracket;
in the locking position of the sliding body, the hooking arm is in the second conformation and said hooking arm is in a second axial position relative to the bracket that is closer to the second end of the through-housing than when in the first axial position; and
in an intermediate position, between the locking and unlocking positions, the hooking arm is in the second conformation and is in the first axial position relative to the bracket.
