A latch having a housing, handle, actuators, pawl and rotary pawl torsion spring and two actuator torsion springs. The rotary pawl torsion spring biases the pawl toward the unlatched or opened position. The handle is pivotally attached to the housing and has two paddles that engage the actuator. The actuator is slidably supported by the housing. Lifting the handle to the open position causes rotating movement of the actuator which in turn causes the pawl to rotate to the unlatched or retracted position.

We claim: 1. A latch for releasably securing a first closure member to a second closure member in a latched position, the latch comprising: a housing adapted for being received in an aperture formed in the first closure member, the housing is composed of a main housing having a bottom surface and a receptacle attached to the bottom surface; a handle pivotally attached to the main housing, the handle being pivotable along a pivot-axis between an open and a closed position, the handle having at least one protuberance; a pawl mounted on the receptacle, the pawl being rotatable about a rotation-axis between a latched and an unlatched position, the rotation-axis being parallel to said pivot-axis; a pawl biasing means for biasing the pawl toward the unlatched position; and an actuator mounted inside the main housing to the bottom surface, the actuator having at least one paddle for engagement with the at least one protuberance of the handle to slide the actuator from a rest position to a retracted position when the handle is pivoted from the closed position and an arm extending through said bottom surface and into the receptacle for engagement and disengagement with the pawl, the at least one paddle and the arm being integral with said actuator; the receptacle having a bottom opening to allow the pawl to interact with the second closure element and a rear opening to allow the arm to move inside and outside the receptacle to interact with the pawl; whereby pivotal movement of the handle when the pawl is in the latched position provides for engagement of the at least one protuberance of the handle with the at least one paddle of the actuator such that the actuator is displaced toward the retracted position, such that the arm is displaced away from said pawl and outside the receptacle to disengage with the pawl thus permitting the biasing force of the pawl biasing device to rotate the pawl to the unlatched position. 2. The latch of claim 1 further comprising at least one actuator biasing means for biasing against the pivoting of the handle from the closed position. 3. The latch of claim 2 wherein the pawl biasing means is a torsion spring. 4. The latch of claim 3 wherein the at least one actuator biasing means is a torsion spring. 5. The latch of claim 2 wherein the handle is ring-shaped. 6. The latch of claim 2, wherein the housing is provided with a flange for contacting the closure member when the latch is provided in the first closure member. 7. The latch of claim 2 wherein the handle has two protuberances and the actuator has two paddles for engagement with a respective protuberance on the handle. 8. The latch of claim 7 wherein the handle is located in a depression of the housing such that the handle is flush with the housing when the handle is in the closed position. 9. The latch of claim 8 wherein the pawl receptacle houses the pawl biasing means.
