Claim 0:
1. A pressure relief valve comprising:
a hand wheel, a cover, a spring, a membrane retainer, a membrane, a body, and an O-ring, wherein,
the body comprises of plurality of horizontal slots spaced apart from each other and disposed radially towards upper portion of the body;
the cover is provided with plurality of clawed structures, spaced apart from each other, disposed radially on the cover, wherein:
each of the clawed structures comprises a first side, a second side, a third side and a fourth side;
each of the clawed structures are connected to the cover towards the first side;
the second side, the third side and the fourth side of each of the clawed structures remain disconnected from the cover, thereby defining a space between the cover and the second side, the third side and the fourth side of each of the clawed structures; and
at least a portion of each of the clawed structures, towards the second side, comprises of a horizontal protrusion that protrudes away from center of the cover;

the membrane retainer comprises of a base structure and a longitudinal member;
the longitudinal member extends from the base structure and is disposed co-axially to the base structure;
the base structure comprises of a side wall extending along a central axis of the membrane retainer;
a gap is defined between the side wall of the base structure and the longitudinal member, wherein the gap is configured to receive at least a portion of the spring;
the longitudinal member, towards a side opposite to the base structure, is provided with a first snap fit mechanism;
the membrane retainer is configured to be received by the membrane, wherein the membrane is in turn configured to be received by the body;
the cover comprises of a through passage, wherein the through passage is configured to receive at least a portion of the longitudinal member in a manner that at least a portion of the longitudinal member interfaces with the through passage of the cover, when the pressure relief valve is assembled;
the hand wheel is provided with a second snap fit mechanism, wherein the hand wheel is coupled to the membrane retainer via the first snap fit mechanism and the second snap fit mechanism;
at least a portion of the cover is configured to be received within the body; and
at least a portion of the plurality of clawed structures comprising the horizontal protrusions provided on the cover are configured to be received by the plurality of horizontal slots on the body, when the cover is received within the body thereby providing a snap fit between the cover and the body.
